High Efficiency Dual Channel / 2 x 3 A Synchronous Buck LED Driver with Integrated High Side Switch and Current Sensing for Automotive Front Lighting

Favorite

Overview

The NCV78825 is a single−chip and high efficient Dual Channel / 2 x 3 A Synchronous Buck LED Driver designed for automotive front lighting applications like high beam, low beam, DRL (daytime running light), turn indicator, fog light, static cornering, etc. The NCV78825 is in particular designed for high current LEDs and provides a complete solution to drive 2 LED strings of up−to 60 V. It includes 2 independent current regulators for the LED strings and required diagnostic features for automotive front lighting with a minimum of external components – the chip doesn’t need any external sense resistor for the buck current regulation. The available output current and voltages can be customized per individual LED string. When morethan 2 LED channels are required on 1 module, then 2, 3 or more devices NCV78825 can be combined; also with NCV787x3 devices – the predecessor of the NCV78825. Thanks to the SPI programmability, one single hardware configuration can support various application platforms.
