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 components. Synchronous rectification and automatic PWM/PFM transitions improve overall solution efficiency. The NCP6343 is in a space saving, low profile 1.99 x 1.34 mm CSP−15 package. Features • Input Voltage Range from 2.3 V to 5.
