Onsemi NCP6332

Description

The NCP6332B/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 1.2 A on an external adjustable from 0.6 V to 3.3 V. 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.
