RT9624G
Single Phase Synchronous Rectified Buck MOSFET Driver
General Description
The RT9624G is a high frequency, synchronous rectified,
single phase MOSFET driver designed for normal MOSFET
driving applications and high performance CPU VR driving
capabilities.
The RT9624G can be supplied from 4.5V to 13.2V. The
applicable power stage VIN range is from 5V to 24V. The
RT9624G also builds in an internal power switch to replace
external bootstrap diode.
The RT9624G can support switching frequency efficiently
up to 500kHz. The RT9624G 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 RT9624G has tri-state
PWM input with shutdown and EN input shutdown
functions, which can force driver to output low UGATE
and LGATE signals.
The RT9624G is available in a small footprint WDFN-8SL
2x2 package.
