Buck Converter - Synchronous 3 MHz, 2 A High Efficiency, Low Ripple, Adjustable Output Voltage NCP6323, NCV6323 www.onsemi.com The NCP/NCV6323 is a synchronous buck converter which is optimized to supply different sub systems of portable applications powered by one cell Liion or three cell Alkaline/NiCd/NiMH MARKING batteries. The devices are able to deliver up to 2 A on an external DIAGRAMS adjustable voltage. Operation with 3 MHz switching frequency allows 1 1 employing small size inductor and capacitors. Input supply voltage XX M WDFN8 feedforward control is employed to deal with wide input voltage (NCV6323) range. Synchronous rectification offer improved system efficiency.
