Description

The NCV78763 is a single−chip, highly 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 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.
