Diodes announced 60V Buck LED Driver with Dimming Functions

Plano, Texas - March 13, 2018 - Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic, analog and mixed-signal semiconductor markets, today announced the AL8862. Featuring a wide input voltage range and integrated power MOSFET, this buck LED driver is well-suited for developers of LED lighting circuits looking to minimize board space and reduce BoM cost, while maintaining 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. Its small profile also means it can 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, such as color mixing, to connected lighting. 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.
