NCP3235GEVB: High Current Sync Buck Converter

The NCP3235GEVB Evaluation Board 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 NCP3235GEVB Evaluation Board is available in 6 mm x 6 mm QFN−40 pin package.
