60V/1A buck LED driver adds dimming to commercial lighting
Supplied in a thermally enhanced SO-8EP package, the AL8862 buck LED driver integrates a power MOSFET and accepts a wide input voltage range.

The compact device minimizes board space and reduce BoM cost while offering excellent analog and PWM dimming functions. With a typical output current accuracy of 5% at up to 1A and 97% efficiency, the AL8862 can operate from an input voltage range between 5V and 60V, making it suitable for commercial, industrial, or architectural lighting. An external control pin accepts either an analog or PWM signal to add dimming capabilities, which brings an additional dimension to connected lighting, such as color mixing. The integrated MOSFET is rated at 60V, making the AL8862 a viable solution for higher power output applications. Leveraging Diodes Incorporated’s proprietary technology, the MOSFET also has an ultra-low Rds(on) of just 0.4Ω, which delivers high efficiency while minimizing the need for external components. Comprehensive protection against possible fault conditions caused by short or open circuits is also included, along with over-temperature protection.
