NCV78902 - High Efficiency 2 Phase Booster LED Driver for Automotive Front Lighting
Ƶ
The NCV78902 is a single−chip and high efficient two phase
Booster designed for automotive front lighting applications like high
beam, low beam, DRL (daytime running light), turn indicator, fog
light, static cornering, etc. The NCV78902 is in particular designed for
high current LEDs and with NCV78935 (triple channel Buck) or
NCV78925 (dual channel Buck) provides a complete solution to drive
multiple LED strings of up−to 60 V.
The device integrates a current-mode voltage booster controller,
realizing a unique input current filter with a limited BOM. The
available output voltage can be customized. Two devices NCV78902
can be combined and the booster circuits can operate together to
function as a multiphase booster (2-phase, 3-phase, 4-phase) in order
to further optimize the filtering effect of the booster and allow cost
effective dimensioning for mid to high power LED systems.
Thanks to the SPI programmability, one single hardware
configuration can support various application platforms.
