MARKING

The NCV6354, a synchronous buck converter, which is optimized

to supply the different sub systems of portable applications powered

by one cell Li−ion or three cell Alkaline/NiCd/NiMH batteries. The

device is 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 offers improved system efficiency. The NCV6354 is in a

space saving, low profile 2.0x2.0x0.75 mm WDFN−8 package.
