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.
