Dual Channel Synchronous-Rectified Buck MOSFET Driver

General Description

Features

^zDrives Four N-Channel MOSFETs

^zAdaptive Shoot-Through Protection

^zInternal Bootstrap Devices

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.

^zSmall SOP-14 Package

^z5V to 12V Gate-Drive Voltages for Optimal Efficiency

^zTri-State Input for Bridge Shutdown

^zSupply Under-Voltage Protection

^zPower ON Over-Voltage Protection

^zRoHS Compliant and 100% Lead (Pb)-Free

The RT9602 can provide flexible gate driving for both high

side and low side drivers. This gives more flexibility of

MOSFET selection.

Applications

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.
