NCP5351

4 A Synchronous Buck

Power MOSFET Driver

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, such as ON Semiconductor’s CS5323, CS5305 or CS5307.

This architecture provides a power supply designer the flexibility to

locate the gate drivers close to the MOSFETs.

The 4.0 A drive capability makes the NCP5351 ideal for minimizing

switching losses in MOSFETs with large input capacitance. Optimized

internal, adaptive nonoverlap circuitry further reduces switching

losses by preventing simultaneous conduction of both MOSFETs.

The floating top driver design can accommodate MOSFET drain

voltages as high as 25 V. Both gate outputs can be driven low, and

supply current reduced to less than 25 mA, by applying a low logic

level to the Enable (EN) pin. An undervoltage lockout function

ensures that both driver outputs are low when the supply voltage is

low, and a thermal shutdown function provides the IC with

overtemperature protection.
