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 the
RT9237/RT9241 series of 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 with 12V. Independent
driving of upper gate through PVCC pin is
achievable. 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 can efficiently
switch power MOSFETs at frequency up to 500KHz.
Switching frequency above 500KHz has to take into
account the thermal dissipation of SOP-8 package.
RT9600 is capable of driving a 3000pF load with a
30ns rise 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.
