Product Overview
NCP6335: Synchronous Buck Converter, Processor Supply, I2C Programming,
Transient Load Helper, 4.0 A
For complete documentation, see the data sheet.
The NCP6335 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 4.0 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 NCP6335 is in a space saving, low profile 2.0 x 1.6 mm CSP 20 package.
