High Efficiency Buck Dual LED Driver with Integrated Current Sensing for Automotive Front Lighting NCV78723 The NCV78723 is a single-chip and high efficient 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 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.

NCV78723 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
