High Efficiency Buck Single LED Driver with Integrated
Current Sensing for Automotive Front Lighting

   The NCV78713 is a single-chip and high efficient Buck Single 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 NCV78713 is in particular designed for high current LEDs and provides a complete solution to drive 1 LED string of up-to 60 V. It includes 1 current regulator for the LED string 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.
