RT9624A  
Single Phase Synchronous Rectified Buck MOSFET Driver  
General Description  
Features  
z Drive Two N-MOSFETs  
The RT9624Ais a high frequency, synchronous rectified,  
single phase MOSFETdriver designed for normal MOSFET  
driving applications and high performance CPU VR driving  
capabilities.  
z Shoot Through Protection  
z Embedded Bootstrap Diode  
z Support High Switching Frequency  
z Fast Output Rising Time  
The RT9624A can be supplied from 4.5V to 13.2V. The  
applicable power stage VIN range is from 5V to 24V. The  
RT9624Aalso builds in an internal power switch to replace  
external bootstrap diode.  
z Tri-State PWM Input for Output Shutdown  
z Enable Control  
z Small SOP-8, SOP-8 (Exposed Pad) and 8-Lead  
WDFN Packages  
The RT9624Acan support switching frequency efficiently  
up to 500kHz. The RT9624A 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 RT9624A  
has tri-state PWM input with shutdown and EN input  
shutdown functions, which can force driver to output low  
UGATE and LGATE signals.  
z RoHS Compliant and Halogen Free  
Applications  
z Core Voltage Supplies forDesktop, Motherboard CPU  
z High Frequency Low ProfileDC/DC Converters  
z High Current Low VoltageDC/DC Converters  
z Core Voltage Supplies forGFX Card  
The RT9624A 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.
