Datasheet Summary
Synchronous Buck Converter
- Step Down
3.0 A
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 ponents. 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.
