NCP6323, NCV6323
3 MHz, 2 A Synchronous
Buck Converter
High Efficiency, Low Ripple, Adjustable
Output Voltage
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 WDFN−8 package.
