Configurable 4.0 A Step  
Down Converter - Transient  
Load Helper  
The NCP6335 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 4.0 A, with programmable output voltage from 0.6 V  
to 1.4 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 NCP6335 is in a space  
saving, low profile 2.0 x 1.6 mm CSP−20 package.
