Synchronous Automotive Buck Regulator
NCV8800 Series
Synchronous Buck Regulator
with 1.0 Amp Switch
The NCV8800 is an automotive synchronous step−down buck
regulator. This part provides an efficient step−down voltage compared
to linear regulators. The NCV8800 uses very few external components
allowing for maximum use of printed circuit board space.
