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.
