NCV78763 Power Ballast and Dual LED Driver for Automotive Front nd Lighting 2 Generation The NCV78763 is a single chip and high efficient smart Power ballast and Dual LED DRIVER designed for automotive front lighting www.onsemi.com 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 SSOP36 EP external components. For each individual LED channel, the output CASE 940AB 132 current and voltage can be customized according to the application requirements. An onchip diagnostic feature for automotive front QFN32 7x7 CASE 485J lighting is provided, easing the safety monitoring from the microcontroller. The device integrates a currentmode voltage booster 1 32 controller, realizing a unique input current filter with a limited BOM. QFN32 When more than two LED channels are required on one module, then CASE 488AM two, three or more NCV78763 devices can be combined, with the possibility for the booster circuits to operate in multiphasemode. This 132 helps to further optimize the filtering effect of the booster circuit and QFNW32 7x7 allows a cost effective dimensioning for mid to high power LED systems. 1 32 CASE 484AG Due to the SPI programmability, one single hardware setup can support QFNW32 5x5 CASE 484AB multiple system configurations for a flexible platform solution approach.
