RT9624E
Single Phase Synchronous Rectified Buck
MOSFET Driver
General Description
The RT9624E is a high frequency, synchronous rectified, single phase
MOSFET driver designed for normal
MOSFET driving applications and high performance CPU VR driving capabilities.
The RT9624E can be supplied from 4.5V to 13.2V. The applicable power stage VIN range is from 5V to 24V. The RT9624E also builds in an internal power switch to replace external bootstrap diode.
The RT9624E can support switching frequency efficiently up to 500kHz. The RT9624E has both 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 RT9624E has tri-state PWM input with shutdown and EN input shutdown functions, which can force driver to output low UGATE and LGATE signals.
The RT9624E is available in a small footprint WDFN-8L 3x3 package.
