NCV78703

Multiphase Booster LED

Driver for Automotive Front

Lighting

The NCV78703 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 NCV78703 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 NCV78703 can be combined and the booster

circuits can operate together to function as a multiphase booster

(2−phase, 3−phase, 4−phase, 5−phase, 6−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.
