Controller IC Chip - MOSFET RT9607PVQ RT9607GVQ RT9607 AJ- chip for laptop- Integrated portable calculator chip(SKU.1-CHIP0994)
Dual Channel Synchronous-Rectified Buck MOSFET Driver
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-tosource 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.
