NCP5355 Datasheet (ON Semiconductor) - 12V Synchronous Buck Power MOSFET Driver

NCP5355, 12V Synchronous Buck Power MOSFET Driver

Pin Pin Symbol Description 1 DRN The switching node common to the high and low *side FETs.

The high *side (TG) driver and supply (BST) are referenced to this pin.

2 TG Driver output to the high *side MOSFET gate.

3 BST Bootstrap supply voltage input.

In conjunction with

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.
