The NCP/NCV6323 is a synchronous buck converter which is

optimized to supply different sub systems of portable applications

powered by one cell Li−ion or three cell Alkaline/NiCd/NiMH

batteries. The devices are able to deliver up to 2 A on an external

adjustable voltage. Operation with 3 MHz switching frequency allows

employing small size inductor and capacitors. Input supply voltage

feedforward control is employed to deal with wide input voltage

range. Synchronous rectification offer improved system efficiency.

The NCP/NCV6323 is in a space saving, low profile 2.0 x 2.0 x

0.75 mm WDFN8 package or a WDFNW8 wettable flank package.
