Dual Channel Synchronous-Rectified Buck MOSFET Driver

General Description

The RT9602 is a, twin power channel MOSFET driver

specifically designed to drive four power N-Channel

MOSFETs in a synchronous-rectified buck converter

topology.

These

drivers

combined

with

a

RT9237/RT9241 series of Multi-Phase Buck PWM

controller 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

protection 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.
