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.
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.
The device integrates a voltage booster controller, realizing a unique input current filter with a limited number of externals.
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.
