RT9625A

Dual-Channel Synchronous Rectified MOSFET Driver

General Description

Features

^zDrive FourN-MOSFETs for Two-Phase PWM Control

The RT9625Ais a high frequency, synchronous rectified,

two phase MOSFET driver designed for normal MOSFET

driving applications and high performance CPU VR driving

capabilities.

^zShoot Through Protection

^zEmbedded Bootstrap Diode

^zSupport High Switching Frequency

z Fast Output Rising Time

The RT9625A can be supplied from 4.5V to 13.2V. The

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

RT9625Aalso builds in internal power switches to replace

external bootstrap diodes.

z Tri-State PWM Input for Output Shutdown

z Enable Control

^zSmall 16-Lead WQFN Package

^zRoHS Compliant and Halogen Free

The RT9625Acan support switching frequency efficiently

up to 500kHz. The RT9625Ahas 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 RT9625Ahas tri-state PWM

input with shutdown and EN shutdown functions, which

can force driver to output low UGATE and LGATE signals.

Applications

z Core Voltage Supplies forDesktop, Motherboard CPU

z High Frequency Low ProfileDC/DC Converters

z High Current Low VoltageDC/DC Converters

z Core Voltage Supplies forGFX Card

Marking Information

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

4x4 package.
