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.
