The RT9624K/RT9624L is a high frequency, synchronous rectified, single phase MOSFET driver designed for normal MOSFET driving applications and high performance CPU VR driving capabilities.The RT9624K/RT9624L can be supplied from 4.5V to 13.2V. The applicable power stage VIN range is from 5V to 24V. The RT9624K/RT9624L also builds in an internal power switch to replace external bootstrap diode.The RT9624K/RT9624L can support switching frequency efficiently up to 500kHz. The RT9624K/RT9624L 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 RT9624K/RT9624L has tri-state PWM input with shutdown and EN input shutdown functions, which can force driver to output low UGATE and LGATE signals.The RT9624K comes in a small footprint with WDFN-8SL 2x2 package. The RT9624L is available in a small footprint WDFN-8L 3x3 package.The recommended junction temperature range is -40°C to 125°C, and the ambient temperature range is -40°C to 85°C.
