NCP5355 12 V Synchronous Buck Power MOSFET Driver The NCP5355 is a dual MOSFET gate driver optimized to drive the gates of both high− and low−side Power MOSFETs in a Synchronous Buck converter. The NCP5355 is an excellent companion to multiphase controllers that do not have integrated gate drivers, such as ON Semiconductor’s NCP5314 or NCP5316. This architecture provides the power supply designer greater flexibility by being able to locate the gate drivers close to the MOSFETs. Driving MOSFETs with a 12 V source as opposed to a 5.0 V can significantly reduce conduction losses. Optimized internal, adaptive nonoverlap circuitry further reduces switching losses by preventing simultaneous conduction of both MOSFETs.
