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