The RT9625B is a high frequency, synchronous rectified, two phase MOSFET driver designed for normal MOSFET driving applications and high performance CPU VR driving capabilities.
The RT9625B can be supplied from 4.5V to 13.2V. The applicable power stage VIN range is from 5V to 23V. The RT9625B also builds in internal power switches to replace external bootstrap diodes.
The RT9625B can support switching frequency efficiently up to 500kHz. The RT9625B has 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 RT9625B has tri-state PWM input with shutdown function, which can force driver to output low UGATE and LGATE signals.
The RT9625 comes in a small footprint with WQFN-16L 4x4 package.
