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.
