NCV8800/D
NCV8800 Series
Synchr onous 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.
