Buck LED driver adds dimming for commercial lighting

The new AL8862 buck LED driver is made up of a wide input voltage range and integrated power MOSFET, and is a solutions well-suited for developers of LED lighting drive circuits looking to minimise board space and reduce BoM cost with excellent analogue 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. Its small profile means it can also be used in appliances of all sizes.

An external control pin accepts either an analogue or PWM signal to add dimming capabilities, which brings an additional dimension to connected lighting, such as colour 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 minimising 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.
