Configurable 5.0 A Step
Down Converter - Transient
Load Helper
The NCP6336 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 5.0 A, with programmable output voltage from 0.6 V
to 1.5 V. It can share the same output rail with another DC−to−DC
converter 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 NCP6336 is in a space
saving, low profile 2.0 x 1.6 mm CSP−20 package.
