Overview
RT9602 Dual Channel Synchronous-Rectified Buck MOSFET Driver General Description The RT9602 is a dual power channel MOSFET driver specifically designed to drive four power N-Channel MOSFETs in a synchronous-rectified buck converter topology.
These drivers combined with RT9237/A and RT9241A/B series of Multi-Phase Buck PWM controllers provide a complete core voltage regulator solution for advanced microprocessors.
The RT9602 can provide flexible gate driving for both high side and low side drivers.
This gives more flexibility of MOSFET selection.
The output drivers in the RT9602 have the capability to drive a 3000pF load with a 40nS propagation delay and 80nS transition time.
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-Channel MOSFETs.
Adaptive shoot-through protect-ion is integrated to prevent both MOSFETs from conducting simultaneously.
The RT9602 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.
