Richtek RT9624AZS

半桥24.5V ~ 13.2V

Overview

The RT9624AZS is a high frequency, synchronous rectified, single phase MOSFET driver designed for normal MOSFET driving applications and high performance CPU VR driving capabilities.The RT9624AZS can be supplied from 4.5V to 13.2V. The applicable power stage VIN range is from 5V to 24V. The RT9624AZS also builds in an internal power switch to replace external bootstrap diode.The RT9624AZS can support switching frequency efficiently up to 500kHz. The RT9624AZS 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 RT9624AZS has tri-state PWM input with shutdown and EN input shutdown functions, which can force driver to output low UGATE and LGATE signals.The RT9624AZS comes in a small footprint with 8-pin packages. The choice of package types includes SOP-8, SOP-8 (Exposed Pad) and WDFN-8L 3x3.
