The RT9611C/D is a high frequency, synchronous rectified, single phase dual MOSFET driver designed to adapt from normal MOSFET driving applications to high performance CPU VR driving capabilities. The RT9611C/D can be utilized under both V<sub>CC </sub>= 5V or V<sub>CC </sub>= 12V applications. The RT9611C/D also builds in an internal power switch to replace external boot strap diode. The RT9611C/D can support switching frequency efficiently up to 500kHz. The RT9611C/D has the UGATE driving circuit and the LGATE driving circuit for synchronous rectified DC/DC converter applications. The driving rising/falling time capability is designed within 30ns and the shoot through protection mechanism is designed to prevent shoot through of high-side and low-side power MOSFETs. The RT9611C/D has PWM tri-state shut down and <span class="overline">OD</span> input shut down functions which can force driver output into high impedance. The difference of the RT9611C and the RT9611D is the propagation delay, t<sub>UGATEpdh</sub>. The RT9611D has comparatively larger t<sub>UGATEpdh</sub> than the RT9611D. Hence, the RT9611C is usually recommended to be utilized in performance oriented applications, such as high power density CPU VR or GPU VR. The RT9611C/D is available in the small footprint WDFN-8L 3x3 package. <hr />
