Designed for automotive LED lighting systems, Diodes’ AL8866Q driver supports buck, boost, buck-boost, and single-ended primary-inductance converter (SEPIC) topologies. This DC-switching LED driver-controller operates over an input voltage range of 4.7 V to 85 V, accommodating 12-V, 24-V, and 48-V battery power rails. It is suitable for applications such as daytime running lights, high/low beams, fog lights, turn signals, and brake lights.

The AL8866Q employs a 400-kHz fixed-frequency peak current-mode control architecture. Spread spectrum frequency modulation enhances EMI performance and aids compliance with the CISPR 25 Class 5 standard.

The device enables analog or PWM dimming via its DIM pin. A 1% reference tolerance ensures better brightness control and matching between lamps. With an analog dimming range of 1% to 100%, the AL8866Q maintains ±12% output current accuracy at 20% dimming. Alternatively, PWM dimming, ranging from 0.1 kHz to 1 kHz, provides a 100:1 dynamic range.

An integrated soft-start function gradually increases the inductor and switch current, minimizing potential overvoltage and overcurrent at the output. The driver also includes an open-drain fault output to signal various fault conditions.

Prices for the AEC-Q100 Grade 1 qualified AL8866Q driver start at $0.48 each in lots of 1000 units.
