... Product Preview Gate Driver for Notebook Power Systems The NCP5359 is a high performance dual MOSFET gate driver optimized to drive the gates of both high-side and low-side power MOSFETs in a synchronous buck converter. Each of the drivers can drive load with propagation delay and 20 ns transition time ...

... The NCP5359 gate driver is a single phase MOSFET driver designed for driving two N-channel MOSFETs in a synchronous buck converter topology. This driver is compatible with the NCP3418B gate drive. This gate drives operation is similar with the NCP3418B, but has two additional new features: Bidirection fault detection and multilevel PWM input ...
