The NEX30606 step-down converter from Nexperia delivers up to 600 mA of output current with an operating quiescent current of just 220 nA. Supporting input voltages from 1.8 V to 5.0 V, the converter offers 16 resistor-settable fixed output voltages and uses constant on-time control for fast transient response.

Ultra-low quiescent current makes the NEX30606 well-suited for consumer wearables like hearing aids, medical sensors, patches, and monitors. It can also be used in battery-powered industrial applications, including smart meters and asset trackers. The converter provides greater than 90% switching efficiency for load currents ranging from 1 mA to 400 mA. Additionally, it has only 10 mV of output voltage ripple when stepping down from 3.6 VIN to 1.8 VOUT.

Nexperia also offers the NEX40400, a step-down converter that combines high efficiency with an operating quiescent current of 60 µA typical. It provides up to 600 mA of output current from a wide 4.5-V to 40-V input voltage range. The device employs pulse frequency modulation for high efficiency at low to mid loads and spread spectrum technology to minimize EMI. Target applications include industrial distributed power systems and grid infrastructure.

Wolfspeed introduced its Gen 4 SiC MOSFET platform, supporting long-term roadmaps for high-power, application-optimized products. Gen 4 offerings include power modules, discrete components, and bare die available in 750-V, 1200-V, and 2300-V classes.

According to Wolfspeed, it is the only producer with both silicon carbide material and silicon carbide device fabrication facilities based in the U.S. This factor is becoming increasingly important under the new U.S. Administration’s increased focus on national security and investment in U.S. semiconductor production.

The Gen 4 platform was designed to improve system efficiency and prolong application life, even in the harshest environments. It is expected to deliver performance enhancements in high-power automotive, industrial, and renewable energy systems, with key benefits including: 

• Holistic system efficiency: Delivering up to a 21% reduction in on-resistance at operating temperatures with up to 15% lower switching losses.
• Durability: Ensuring reliable performance, including a short-circuit withstand time of up to 2.3 µs to provide additional safety margin.
• Lower system cost: Streamlining design processes to reduce system costs and development time.

Gen 4 SiC power modules, discrete components, and bare die are available now through Wolfspeed’s distributor network.

No idea what I was doing. Attempted to replace 5 capacitors that split from capacitor plague. Burned myself twice, the whole job was hideous. The Xbox booted up, and it working fine! 10/10 will burn myself again! If you're unsure I'd you can do it or not, just go for it, you can do it! submitted by /u/wowreallyyyy [link] [comments]

In its 2025 predictions for gallium nitride (GaN) power semiconductors, Infineon Technologies AG of Munich, Germany highlights that GaN will be a game-changing material for energy efficiency and decarbonization across the consumer, mobility, residential solar, telecoms, and AI data-center sectors, as GaN enables efficient performance, smaller size, lighter weight, and lower overall cost. While USB-C chargers and adapters have been the forerunners, GaN is now on its way to reaching tipping points in its adoption in further industry sectors, driving the market for GaN-based power semiconductors...

A lightweight runtime security code embedded into a system-on-chip (SoC) for Internet of Things (IoT) applications. That’s the outcome of a collaboration between MediaTek and Italy-based embedded IoT security firm Exein. EE Times’ Editor-in-Chief Nitin Dahad spoke to Gianni Cuozzo, founder and CEO of Exein, to know more about this collaboration that ensures security is an integral part of the development process rather than an afterthought.

Cuozzo, who founded the company in 2018 to address the emerging mandatory cybersecurity regulations, claims it’s the world’s first integration between a chip manufacturer and runtime security software. He also claims it’s the lightest runtime agent available, whether running at the edge or the cloud.

The flux arrived early, as well as some cheap helping hands. I used wire instead of blobs and actually repaired the traces instead of the in between this time. The wires are made out of a torn up desoldering wick, and I used an insulated cable below because I accidentally ripped part of the trace off. Using flux is amazing, everything just starts sticking to where it needs to go (the wires spontaniously allign). I cleaned everything with some vodka afterwards. All buttons on the drone controller work again :) submitted by /u/Doughnut_Opposite [link] [comments]
