The NCP6335G is a synchronous buck converter 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 5.0 A pulse current, with programmable output voltage from 0.6 V to 1.4 V. It can share the same output rail with another DC−to−DC converter and works as a transient load helper. Operation at a 3 MHz switching frequency allows the use of small components. Synchronous rectification and automatic PWM/PFM transitions improve overall solution efficiency. The NCP6335G is in a space saving, low profile 2.0 x 1.6 mm CSP−20 package.
