Diodes' New AL8862 Buck LED Driver Adds Dimming for Commercial Lighting

A wide input voltage range and integrated power MOSFET make the AL8862 buck LED driver a solution well-suited for developers of LED lighting drive circuits looking to minimize board space and reduce BoM cost with excellent analog and PWM dimming functions.

With a typical output current accuracy of 5% at up to 1 A and 97% efficiency, the AL8862 can operate from an input voltage range between 5 V and 60 V, making it suitable for commercial, industrial, or architectural lighting. Its small profile means it can also be used in appliances of all sizes.

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 60 V, 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.

The AL8862 is supplied in a thermally enhanced SO-8EP package and prices at $0.30 at volumes of 10K.
