RT9624B

Single Phase Synchronous Rectified Buck MOSFET Driver

General Description

Features

 Drive Two N-MOSFETs

The RT9624B 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 Diode

 Support High Switching Frequency

 Fast Output Rising Time

The RT9624B can be supplied from 4.5V to 13.2V. The

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

IC also builds in an internal power switch to replace

external bootstrap diode.

 Tri-State PWM Input for Output Shutdown

 Small SOP-8, SOP-8 (Exposed Pad) and 8-Lead

WDFN Packages

 RoHS Compliant and Halogen Free

The RT9624B can support switching frequency efficiently

up to 500kHz. The IC has both the UGATE and LGATE

driving circuits for synchronous rectifiedDC/DC converter

applications. The shoot through protection mechanism is

designed to prevent shoot through between high side and

low side power MOSFETs. The RT9624B has tri-state

PWM input with shutdown function, 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

The RT9624B comes in a small footprint with 8-pin

packages. The choice of package types includes SOP-8,

SOP-8 (Exposed Pad) and WDFN-8L 3x3.
