DC-DC LED Drivers | NCV78935
概览
The NCV78935 is high efficient Synchronous 3 channel Buck LED Drivers designed for automotive front lighting applications like High beam, low beam, DRL (daytime running light), turn indicator, fog light, static cornering, etc. The NCV78935 is in particular Designed for high current LEDs and provides a complete solution to drive three LED strings of up-to 60 V with minimum of External components.
When more LED channels are required on one module, more NCV78925 or NCV78935 devices can be combined, also together with NCV78964 or NCV78902 devices which incorporate the booster circuits with possibility to operate in multiphase-mode. This Helps to further optimize 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.
