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.

MARKING

DIAGRAMS

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.

The floating top driver design can accommodate MOSFET drain

voltages as high as 26 V. Both gate outputs can be driven low 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.
