Buck Converter Synchronous
3 MHz, 2 A
NCP6324, NCV6324
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.
