Ensuring stable power management is crucial in modern electronics, and the power supply rejection ratio (PSRR) plays a key role in achieving this. This article serves as a practical guide to measuring PSRR for power management ICs (PMICs) and offering clear and comprehensive instructions.

PSRR reflects a circuit’s ability to reject fluctuations in its power supply voltage, directly impacting performance and reliability. By understanding and accurately measuring this parameter, engineers can design more robust systems that maintain consistent operation even under varying power conditions.

Figure 1 Here is the general methodology to measure PSRR. Source: Renesas

PSRR is a vital parameter that assesses an LDO’s capability to maintain a consistent output voltage amidst variations in the input power supply. Achieving high PSRR is crucial in scenarios in which the input power supply experiences fluctuations, thereby ensuring the dependability of the output voltage. Figure 1 below illustrates the general methodology for measuring PSRR.

The mathematical expression to calculate the PSRR value is:

PSRR = 20 log10 VIN/VOUT

Where VIN and VOUT are the AC ripple of the input and output voltage, respectively.

Equipment and setup

To ensure an accurate measurement of the PSRR, it’s essential to set up the test environment with precision. The following design outlines the use of the listed equipment to establish a robust and reliable test configuration.

First, connect the power supply—in our case it’s a Keithley 2460—to the input of the Picotest J2120A line injector. The power supply should be configured to generate a stable DC voltage while the AC ripple component is provided by a Bode 100 network analyzer output using the J2120A line injector to simulate power supply variations.

Note that J2120A line injector includes an internally biased N-channel MOSFET. This means that there is a voltage drop between the J2120A input and output. The voltage drop is non-linear, and its dependency is shown on Figure 2. This means that each time the load current is adjusted, the source power supply must also be adjusted to maintain a constant DC output voltage at the J2120A terminals.

Figure 2 J2120A’s resistance and voltage drop is shown versus output current. Source: Renesas

For example, to get 1.2 V at the input of the LDO regulator, and depending on the current load, it might be required to set the voltage on the input of the line injector from 2.5 V to 3.5 V. The MOSFET operates as open loop so not to become unstable when connected to the external regulator.

Next, a digital multimeter is used to monitor both the input and output voltages of the PMIC. Ensure that proper grounding is used, and minimal interference is present in the connections to maintain measurement integrity.

Finally, a Bode 100 from Omicron Lab is used to record and analyze the measurements. This data can be used to compute the PSRR values and evaluate the PMIC’s ability to maintain a stable output despite variations in the input supply.

By carefully following this setup, one can ensure accurate and reliable PSRR measurements, contributing to the development of high-performance and dependable electronic systems.

The PSRR measurement is performed with the Bode 100. The Gain/Phase measurement type should be chosen in the Bode Analyzer Suite software as shown on Figure 4.

Figure 4 Start menu is shown in the Bode Analyzer Suite software. Source: Renesas

Set the Trace 1 format to Magnitude (dB).

Figure 5 This is how to set Trace 1. Source: Renesas

To get the target PSRR measurement, choose the following settings in the “Hardware Setup”:

1. Frequency: Change the Start frequency to “10 Hz” and Stop frequency to “10 MHz”.
2. Source mode: Choose between Auto off or Always on. In Auto off mode, the source will be automatically turned off whenever it’s not used (when a measurement is stopped). In Always on mode, the signal source stays on after the measurement has finished. This means that the last frequency point in a sweep measurement defines the signal source frequency and level.
3. Source level: Set the constant source level to “-16 dB” or higher for the output level. The unit can be changed in the options. By default, the Bode 100 uses dBm as the output level unit. 1 dBm equals 1 mW at 50 Ω load. “Vpp” can be chosen to display the output voltage in peak-to-peak voltage. Note that the internal source voltage is two times higher than the displayed value and valid when a 50 Ω load is connected to the output.
4. Attenuator: Set the input attenuators 20 dB for Receiver 1 (Channel 1) and 0 dB for Receiver 2 (Channel 2).
5. Receiver bandwidth: Select the receiver bandwidth used for the measurement. Higher receiver bandwidth increases the measurement speed. Reduce the receiver bandwidth to reduce noise and to catch narrow-band resonances.

Before starting the measurement, the Bode 100 needs to be calibrated. This will ensure the accuracy of the measurements. Press the “Full Range Calibration” button as shown in Figure 7. To achieve maximum accuracy, do not change the attenuators after external calibration is performed.

For all LDOs:

1. The input capacitor will filter out some of the signals injected into the LDO, so it’s best to remove the input capacitors for the tested LDO or keep one as small as possible.
2. Configure the network analyzer; use the power supply to power the line injector and connect the output of the network analyzer to the open sound control (OSC) input of the line injector.
3. Power up the device under test (DUT) and configure the tested LDO’s output voltage. To prevent damage to the PMIC, the LDO’s input voltage should be less than or equal to the max input voltage. It’s highly recommended to power up the LDO without a resistive load, then apply the load and adjust the input voltage.
4. Configure the LDO VOUT as specified in Table 2.
5. Enable the LDO under test and use a voltmeter to check the output voltage.
6. To ensure that the start-up current limit does not prevent the LDO from starting correctly, connect the resistive load to the LDO once the VOUT voltage has reached its max level.
7. Adjust the voltage at the J2120A OUT terminals to their target VIN.
8. Connect the first channel (CH1) of the network analyzer to the input of the LDO under test using a short coaxial cable.
9. Connect the second channel (CH2) of the network analyzer to the output of the LDO under test using a short coaxial cable.
10. Monitor the output voltage of the line injector on an oscilloscope. Perform a frequency sweep and check that the minimum input voltage and an appropriate peak to peak level for test are achieved. Make sure that the AC component is 200 mVpp or lower.

Figure 11 This simplified example shows headroom impact on the ripple magnitude. Source: Renesas

Note that headroom for the PSRR is not the same as the dropout voltage parameter (Vdo) specified in the datasheets (see Figure 11). Headroom in the context of PSRR refers to the additional voltage margin above the output voltage that an LDO requires to effectively reject variations in the input voltage.

Essentially, it ensures that the LDO can maintain a stable output despite fluctuations in the input power supply. Dropout voltage (Vdo), on the other hand, is a specific parameter defined in the datasheets of LDOs.

It’s the minimum difference between the input voltage (VIN) and the output voltage (VOUT) at which the LDO can still regulate the output voltage correctly under static DC conditions. When the input voltage drops below this minimum threshold, the LDO can no longer maintain the specified output voltage, leading to potential performance issues.

Figure 12 Example highlights applied ripple and its magnitude with DC offset for LDO’s input. Source: Renesas

11. Set up the network analyzer by using cursors to measure the PSRR at each required frequency (1 kHz, 100 kHz and 1 MHz). Add more cursors if needed to measure peaks as shown in Figure 13.

Figure 13 This is how design engineers can work with cursors. Source: Renesas

12. Capture images for each measured condition.

Figure 14 Example shows captured PSRR graph for the SLG51003 LDO. Source: Renesas

Figure 15 Bench measurement setup is shown for the SLG51003 PSRR.

Clear and precise PSRR measurement

This methodology provides a clear and precise approach for measuring the PSRR for the SLG5100X family of PMICs using the Omicron Lab Bode 100 and Picotest J2120A. Accurate PSRR measurements in the 10 Hz to 10 MHz frequency range are crucial for validating LDO performance and ensuring robust power management.

The accompanying figures serve as a valuable reference for setup and interpretation, while strict adherence to these guidelines enhances measurement reliability. By following this framework, engineers can achieve high-quality PSRR assessments, ultimately contributing to more efficient and reliable power management solutions.

My wife’s 2018 Land Rover Discovery looks something like this:

with at least one important difference, related (albeit not directly) to the topic of this writeup: hers doesn’t have fog lights. They’re the tiny shiny things at the upper corners of the front bumper of the “stock” photo, just below the air intake “scoops”. In her case, bumper-colored plastic pieces take their places (and the on/off control switch normally at the steering wheel doesn’t exist either, of course, nor apparently does the intermediary wiring harness).

More generally, the from-factory headlights were ridiculously dim yellow-color temperature things, halogen-based and H7 in form factor. This vehicle, unlike most (I think) uses two identical pairs of H7, albeit aimed differently, one for the “low” (i.e. “dipped” or “driving”) set and the other for the “high” (i.e. “full” or “bright”) set. Land Rover didn’t switch to LED-based headlights until 2021, but the halogens were apparently so bad that at least one older-generation owner contracted with a shop to update them with the newer illumination sets both front and rear.

On a hunch, I purchased a set of Auxito LED-based replacement bulbs from Amazon for ~$30, figuring them to be a fiscally rationalizable experiment regardless of the outcome success-or-not. These were the fanless 26W 800 lumen variant found on the manufacturer’s website:

Here’s an accompanying “stock” video:

Auxito also sells a brighter (1000 lumens), more power-demanding (30W) variant with a nifty-looking integrated cooling fan:

When they arrived, they slipped right into where the halogens had been; the removal-and-replacement process was a bit tedious but not at all difficult. I’d been pre-warned from my preparatory research (upfront in the manufacturer’s product page documentation both on its and Amazon’s websites, in fact, which was refreshing) that dropping in LEDs in place of halogens can cause various issues, resulting from their ongoing connections to the vehicle’s CAN bus communication network system, for example:

LED upgrade lights are great. They’re rugged, they last far longer than conventional bulbs, and they offer brilliant illumination. But in some vehicles, they can also trigger a false bulb failure warning. Some cars use the vehicle’s computer network (CANbus) system to verify the functioning of the vehicle’s lights. Because LED bulbs have a lower wattage and draw much less power than conventional bulbs, when the system runs a check, the electrical resistance of an LED may be too low to be detected. This creates a false warning that one of the lights has failed.

Here’s the other common problem:

A lot of auto manufacturers use PWM (or pulse width modulation) to precisely control the voltage to a bulb. One of the benefits of doing this is to improve bulb life. These quick, voltage pulses (PWM) do not give a bulb filament time to cool down and dim, so for halogen bulbs the pulses are not noticeable. However, with an LED bulb, these pulses are enough to turn the LEDs off and on very quickly, which results in a flashing of the light.

Philips sells LED CANbus adapters which claim to fix both issues. Auxito also says that it will ship free adapters to customers who encounter problems, albeit noting (in charming broken English):

Built-in upgraded CANBUS decoder, AUXITO H7 bulbs is perfectly compatible with 98% of vehicles. A few extremely sensitive vehicles may require an additional decoder.

I’m delighted to be able to say—hopefully not jinxing myself in the process—that I’m apparently one of those 98%. The LED replacement bulbs fired up glitch-free and have remained problem-less for the multiple months that we’ve used them so far. The color temperature mismatch between them (6500K) and the still-present halogen high beams, which we sometimes also still need to use and which I’m guessing are closer to 3000K, results in a merged  illumination pattern beyond the hood that admittedly looks a bit odd, but I’ve bought a second Auxito LED H7 headlight set that I plan to install in the high-beam bulb sockets soon (I promise, honey…).

I’ve also bought a third set, actually, one bulb for use as a spare and the other for future-teardown purposes. In visual sneak-peek preparation, here are some photos of an original halogen bulb, as usual accompanied by a 0.75″ (19.1 mm) diameter U.S. penny for size comparison purposes:

and the LED-based successor, first boxed (I’m only showing the meaningful-info box sides):

and then standalone:

For above-and-beyond (if I do say so myself) reader-service purposes, I also scanned the user manual, whose PDF you can find here:

And with that hopefully illuminating (see what I did there?) info out of the way, I’ll close for today, with an as-usual invitation for reader-shared thoughts in the comments!

Electromagnetic interference (EMI) and radiofrequency interference (RFI) refer to electromagnetically generated noise that can interfere with products’ performance and reliability. RFI is a subset of EMI that refers to radiated emissions such as those from power or communication lines.

Design engineers must strategically reduce EMI and RFI at every opportunity, especially since some sources are naturally occurring and impossible to remove from the environment.

Engineering professionals should begin by using design choices that mitigate these unwanted effects. For example, trace placement can reduce undesirable interference since a PCB’s traces carry current from drivers and receivers.

One widely established tip is to keep the distance between traces at least several times the width of individual traces. Similarly, designers should separate signal-related traces from others, including those associated with audio or video transmission.

The design-centered tools can help all parties test different possibilities to find the ones most likely to work in the real world. One such tool allows designers to ease the transition from design to manufacture by creating a digital twin of the production environment. This format-agnostic platform also enables real-time collaboration, shortening the time required for clients to approve designs.

Select appropriate internal filters and shields

Besides following design-related best practices, professionals building electronics while reducing EMI and RFI must identify opportunities to suppress and deflect them without adding too much weight to the devices. That is especially important in cases where people build electronics for aerospace and automotive applications.

The general process is identifying trouble spots after making all appropriate design-related improvements. Engineers should then proceed by applying filtering circuits on the inputs and outputs. Next, they can apply shields. These products surround at-risk components, creating a protective barrier.

The shields are typically metal or polyester, and engineers use industrial machines to form them into the desired shapes. While filters allow harmless frequencies to pass through them, shields block and redistribute EMI to mitigate their potentially dangerous effects.

A particular point is that filters only block EMI moving through physical connections such as cables. EMI transmission occurs through the air and needs no entry point. Additionally, designers will get the best results by scrutinizing how the electronic device functions and acting accordingly. One possibility is to install filters at heat sinks to control the EMI that would otherwise come through the holes that promote thermal management.

Consider electrospray technologies

An emerging EMI protection is to deposit electrospray materials onto surfaces or components. In addition to its cost-effectiveness, this solution offers customizable results because engineers can add as much as their applications require.

Although many of these efforts are in the early stages, design engineers should monitor their progress and consider how to incorporate them into their future products. One example comes from a mechanical engineering doctoral student exploring how to apply protective layers to electronics by dispensing aerosols or liquids onto them with electricity. This approach could be especially valuable to manufacturers that create increasingly small products for which traditional shielding techniques are less suitable.

The student argues that electrospray technologies for shielding can open opportunities for protecting miniaturized devices. Her technique deposits a silver layer onto the surface, minimizing the space and costs required to protect devices.

This strategy and similar efforts could also be ideal for engineers who want to safeguard delicate electronics without adding weight. Many consumers perceive lightweight, tiny devices as more innovative than heavier, larger ones. Electrospray caters to these devices while meeting modern manufacturing requirements.

Take project-specific approaches

In addition to following these tips, electronics designers must always engage with their clients throughout their work. Such engagements allow engineering professionals to understand specific needs and identify the most effective ways to achieve successful outcomes.

What worked well in one case may be less suitable for others that seem similar. However, client feedback ensures everyone is on the same page.
