1 / 15 page  RT9607/A 1 DS9607/A-07 April 2011 www.richtek.com Dual Channel Synchronous-Rectified Buck MOSFET Driver Ordering Information General Description The RT9607/A is a dual power channel MOSFET driver specifically designed to drive four power N-MOSFETs in a synchronous-rectified buck converter topology. These drivers combined with RichTek ’ s series of Multi-Phase Buck PWM controllers provide a complete core voltage regulator solution for advanced microprocessors. The RT9607/A can provide flexible gate driving for both high side and low side drivers. This gives more flexibility of MOSFET selection. The output drivers of the part are capble to driver a 3nF load in 30/40ns rising/falling time with fast propagation delay from input transition to the gate of the power MOSFET. This device implements bootstrapping on the upper gates with only a single external capacitor required for each power channel. This reduces implementation complexity and allows the use of higher performance, cost effective, N-MOSFETs. Adaptive shoot-through protect-ion is integrated to prevent both MOSFETs from conducting simultaneously. The RT9607/A can detect high side MOSFET drain-to- source electrical short at power on and pull the 12V power by low side MOS and cause power supply to go into over current shutdown to prevent damage of CPU. RT9607 has longer UGATE/LGATE dead time which can drive the MOSFETs with large gate RC value, avoiding the shoot-through phenomenon. RT9607A is targeted to drive small gate RC value MOSFETs and performs better efficiency. Features Drives Four N-MOSFETs Adaptive Shoot-Through Protection Propagation Delay 40ns Support High Switching Frequency Fast Output Rise Time 5V to 12V Gate-Drive Voltages for Optimal Efficiency Tri-State Input for Bridge Shutdown Supply Under-Voltage Protection RoHS Compliant and 100% Lead (Pb)-Free Applications Core Voltage Supplies for motherboard/desktop PC microprocessor core power High Frequency Low Profile DC-DC Converters High Current Low Voltage DC-DC Converters Note : Richtek products are : RoHS compliant and compatible with the current require- ments of IPC/JEDEC J-STD-020. Suitable for use in SnPb or Pb-free soldering processes. Marking Information For marking information, contact our sales representative directly or through a Richtek distributor located in your area.
