The NCP/NCV6324, a family of synchronous buck converters,

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 and automatic

PWM/PFM power save mode offer improved system efficiency. The

NCP/NCV6324 is in a space saving, low profile 2.0 x 2.0 x 0.75 mm

WDFN8 package or a WDFNW8 wettable flank package.
