RT9625B

Dual-Channel Synchronous Rectified MOSFET Driver

General Description

Features

^Drive FourN-MOSFETs for Two-Phase PWM Control

The RT9625B is a high frequency, synchronous rectified,

two phase MOSFET driver 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 RT9625B can be supplied from 4.5V to 13.2V. The

applicable power stage VIN range is from 5V to 23V. The

RT9625B also builds in internal power switches to replace

external bootstrap diodes.

 Tri-State PWM Input for Output Shutdown

^Small 16-Lead WQFN Package

^RoHS Compliant and Halogen Free

The RT9625B can support switching frequency efficiently

up to 500kHz. The RT9625B has 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 RT9625B 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

Marking Information

The RT9625 comes in a small footprint with WQFN-16L

4x4 package.
