NCV6354

NCV6354 3MHz, 2A Fixed-Frequency Synchronous Buck Converter High Efficiency, Low Ripple, Adjustable Output Voltage http://onsemi.com MARKING DIAGRAM 1 ADMG G 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.
