Overview
Multiphase Booster LED Driver for Automotive Front Lighting NCV78702 The NCV78702 is a single−chip and high efficient booster for smart Power ballast and 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 NCV78702 is in particular designed for high current LEDs and with NCV78723 (dual channel buck)/713 (single channel) provides a complete solution to drive multiple LED strings of up−to 60 V.
It includes a current−mode voltage boost controller which also acts as an input filter with a minimum of external components.
The available output voltage can be customized.
Two devices NCV78702 can be combined and the booster circuits can operate together to function as a multiphase booster (2−phase, 3−phase, 4−phase) in order to further optimize the filtering effect of the booster and lower the total application BOM cost for higher power.
Thanks to the SPI programmability, one single hardware configuration can support various application platforms.
