NCP6338: Synchronous Buck Converter, Processor Supply, I2C Programming, Remote Sense, 6.0 A
The NCP6338 is a synchronous buck converter optimized to supply recent micro processors (ARM core processor, GPU) 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 6 A of programmable voltage ranging from 0.6 V to 1.4 V. Synchronous rectification and automatic PFM/PWM transition offer improved system efficiency. Operation at a 3 MHz switching frequency allows the use of small form factor external components. The NCP6338 is in a space saving, low profile 2.06 x 2.46 mm CSP-30 package.
