Overview
NCP6335G Configurable 5.
0 A Step Down Converter - Transient Load Helper 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.
