NCP6334: Synchronous Buck Converter, 3 MHz, 2.0 A

The NCP6334B/C, 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 or a fixed output voltage range from 0.6 V to 3.3 V upon request. Operation with 3 MHz switching frequency allows employing small size inductor and capacitors. Synchronous rectification and automatic PWM/PFM power save mode offer improved system efficiency. The NCP6334B/C is in a space saving, low profile 2.0 x 2.0 x 0.75 mm WDFN-8 package.
