Synchronous Buck Converter - Step Down 3.0 A NCP6343 The NCP6343 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 3.0 A, with programmable output voltage from 0.6 V to 1.4 V.

It can share the same output rail with another DCDC and works as a transient load helper.

Operation at a 3 MHz switching frequency allows the use of small
