The RT9624BZQW is a single-phase high frequency synchronous rectified MOSFET Driver designed for normal MOSFET driving applications and high performance CPU VR driving capabilities. It can be supplied from 4.5 to 13.2V. The applicable power stage VIN range is from 5 to 24V. The IC also builds in an internal power switch to replace external bootstrap diode. It can support switching frequency efficiently up to 500kHz. The IC has both the 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 RT9624B has tri-state PWM input with shutdown function, which can force driver to output low UGATE and LGATE signals.
