Overview: DATA SHEET www.onsemi.com High Efficiency Single-chip 2 Phase Booster and Synchronous Dual Buck LED Driver for Automotive Front Lighting
NCV78964
The NCV78964 is a single-chip and high efficient 2 phase Booster and Synchronous Dual-Channel Buck LED Driver designed for automotive front lighting applications like high beam, low beam, DRL (daytime running light), turn indicator, fog light, static cornering, etc. The NCV78964 is in particular designed for high current LEDs and provides a complete solution to drive two LED strings of up-to 60 V with minimum of external components.
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 NCV78964 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.
Thanks to the SPI programmability, one single hardware configuration can support various application platforms.
