Description

NV78825−0

AWLYYWWG

The NCV78825 is a single−chip and high efficient Synchronous

Buck Dual 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 more

than 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.
