NCV78713 - High Efficiency Buck Single LED Driver

Description

Component Function Typical Value Unit L_BCK Buck Regulator Coil (see Buck Regulator Chapter for Details) 47 mH C_BCK Buck Regulator Output Capacitor (see Buck Regulator Chapter for Details) 220 nF C_M3V Capacitor for M3V Regulator (see Table 6 VBOOSTM3V) nF C_DD C_LED VDD

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.

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.
