Product Description
The NCP5351 is a dual MOSFET gate driver optimized to drive the gates of both high-side and low-side Power MOSFETs in a Synchronous Buck converter. The NCP5351 is an excellent companion to multiphase controllers that do not have integrated gate drivers. This architecture provides a power supply designer the flexibility to locate the gate drivers close to the MOSFETs. The 4 A drive capability makes the NCP5351 ideal for minimizing switching losses in MOSFETs with large input capacitance. Optimized internal, adaptive non-overlap circuitry further reduces switching losses by preventing simultaneous conduction of both MOSFETs.
