NCV78763

Power Ballast and Dual LED

Driver for Automotive Front

Lighting 2^ndGeneration

The NCV78763 is a single−chip and high efficient smart Power

ballast and Dual LED DRIVER designed for automotive front lighting

applications like high beam, low beam, daytime running light (DRL),

turn indicator, fog light, static cornering and so on.

www.onsemi.com

The NCV78763 is a best fit for high current LEDs and provides a

complete solution to drive two strings up to 60 V, by means of two

internal independent buck switch channel outputs, with a minimum of

external components. For each individual LED channel, the output

current and voltage can be customized according to the application

requirements. An on−chip diagnostic feature for automotive front

lighting is provided, easing the safety monitoring from the

microcontroller. The device integrates a current−mode voltage booster

controller, realizing a unique input current filter with a limited BOM.

When more than two LED channels are required on one module, then

two, three or more NCV78763 devices can be combined, with the

possibility for the booster circuits to operate in multiphase−mode. This

helps to further optimize the filtering effect of the booster circuit and

allows a cost effective dimensioning for mid to high power LED systems.

Due to the SPI programmability, one single hardware setup can support

multiple system configurations for a flexible platform solution approach.
