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 up to 3 nF load with a 25 ns propagation delay and 20 ns

transition time.

Adaptive nonoverlap and power saving operation circuit can

provide a low switching loss and high efficiency solution for notebook

and desktop systems.

MARKING

DIAGRAMS

A high floating top driver design can accommodate VBST voltage

as high as 35 V, with transient voltages as high as 35 V. Bidirectional

EN pin can provide a fault signal to controller when the gate driver

fault detect under OVP, UVLO occur. Also, an undervoltage lockout

function guarantees the outputs are low when supply voltage is low,

and a thermal shutdown function provides the IC with

overtemperature protection.
