NCP3235

High Current Synchronous

Buck Converter

The NCP3235 is a high current, high efficiency voltage mode

synchronous buck converter which operates from 4.5 V to 23 V input

and generates output voltages down to 0.6 V at up to 15 A continuous

current. It has two operation modes: FCCM and automatic

CCM/DCM. In automatic CCM/DCM mode, the controller can switch

smoothly between CCM and DCM, where converter runs at reduced

switching frequency to achieve much higher efficiency at light load.

The NCP3235 is available in 6 mm x 6 mm QFN−40 pin package.
