RT9624C

Single Phase Synchronous Rectified Buck MOSFET Driver

General Description

Features

 Drive Two N-MOSFETs

The RT9624C is a high frequency, synchronous rectified,

single phase MOSFETdriver designed for normal MOSFET

driving applications and high performance CPU VR driving

capabilities.

 Shoot-Through Protection

 Embedded Bootstrap Switch

 Support High Switching Frequency

 Fast Output Rising Time

The RT9624C can be supplied from 4.5V to 13.2V. The

applicable power stage VIN range is from 5V to 24V. The

RT9624C also builds in an internal power switch to replace

external bootstrap diode.

 Tri-State PWM Input for Output Shutdown

 Enable Control

 Small 8-Lead WDFN Package

 RoHS Compliant and Halogen Free

The RT9624C can support switching frequency efficiently

up to 500kHz. The RT9624C has both the UGATE and

LGATE driving circuits for synchronous rectified DC/DC

converter applications. The shoot through protection

mechanism is designed to prevent shoot through between

high side and low side power MOSFETs. The RT9624C

has tri-state PWM input with shutdown and EN input

shutdown functions, which can force driver to output low

UGATE and LGATE signals.

Applications

 Core Voltage Supplies forDesktop, Motherboard CPU

 High Frequency Low ProfileDC/DC Converters

 High Current Low VoltageDC/DC Converters

 Core Voltage Supplies forGFX Card
