Single Phase Synchronous Rectified Buck MOSFET Driver

RT9614C

Update Alert Share

The RT9614C is a high performance, synchronous rectified, single phase MOSFET driver designed for general MOSFET driving applications and high performance CPU VR driving capabilities.

The RT9614C can be supplied from 4.5V to 13.2V. The applicable power stage VIN range is from 5V to 24V. The RT9614C also builds in an internal power switch to replace external bootstrap diode.

The RT9614C can support switching frequency efficiently up to 500kHz. The RT9614C has both the UGATE and LGATE driving circuits for synchronous rectified DC-DC converter applications. The pre-OVP protection is designed to protect system when output has high voltage and shoot through protection mechanism is designed to prevent shoot through between high side and low side power MOSFETs. The RT9614C has tri-state PWM input with shutdown and EN input shutdown functions, which can force driver to output low UGATE and LGATE signals.
