The NCP6343 is a synchronous buck converter optimized to supply recent micro processors (ARM core processor, GPU), memories, that demand high power at low voltages 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 could share the same output rail with another DCDC/LDO 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.
