Synchronous-Rectified Buck MOSFET Drivers

General Description

The RT9600 is a high frequency, dual MOSFET

driver specifically designed to drive two power N-

Channel MOSFETs in a synchronous-rectified buck

converter topology. This driver combined with a

RT9237 Multi-Phase Buck PWM controller form a

complete

core-voltage

regulator

solution

for

advanced microprocessors.

The RT9600 drives both the lower/upper gate in a

synchronous-rectifier bridge to 12V. Independent

driving of upper gate through PVCC pin is

achievable. Recommended PVCC ranges are from

8 to 12V for Rds(on) concern. This drive-voltage

flexibility provides the advantage of optimizing

applications involving trade-offs between switching

losses and conduction losses.

The output drivers in the RT9600 have the capacity

to efficiently switch power MOSFETs at frequencies

up to 2MHz. Each driver is capable of driving a

3000pF load with a 30ns propagation delay and

50ns

transition

time.

RT9600

implements

bootstrapping on the upper gate with only an

external

capacitor

required.

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.
