RT9625A
Dual-Channel Synchronous Rectified MOSFET Driver
General Description
Features
Drive 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.
Shoot Through Protection
Embedded Bootstrap Diode
Support High Switching Frequency
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.
Tri-State PWM Input for Output Shutdown
Enable Control
Small 16-Lead WQFN Package
RoHS 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
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
