NCV78663

Power Ballast and Dual LED

Driver for Automotive Front

Lighting

The NCV78663 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.

The NCV78663 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 channels, with a minimum of

external components.

MARKING

DIAGRAM

For each channel, the output current and voltage can be customized

according to the application requirements. Diagnostic feature for

automotive front lighting is provided on−chip.

AWLYYWWG

The device integrates a voltage booster controller, realizing a unique

input current filter with a limited number of externals.

CASE 940AB

The NCV78663 can be used in stand−alone mode or together with a

companion microcontroller allowing maximum flexibility. Depending

on the voltage and current of the connected LED string, the LED

ballast parameters can be adapted by writing the SPI settings in the

device, as such that no hardware changes are required.
