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 lowside 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.
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.
The NCP5355 has the same pinout as the NCP5351 5.0 V
Gate Driver.
