NCV78713
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. The available
output current and voltage can be customized for the LED string.
When more than 1 LED channel is required on 1 module,
the NCV78713 can be combined with NCV78723 devices,
incorporating Buck Dual LED Driver. Thanks to the SPI
programmability, one single hardware configuration can support
various application platforms.
