4A Driver
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 �A, 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 NCP5351 is pin−to−pin compatible with the SC1205 and is
available in a standard SO−8 package and thermally enhanced
DFN−10.
