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 modu

Applications

* like high beam, low beam, DRL (daytime running light), turn indicator, fog light, static cornering, etc. The NCV78723 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 string
