Preliminary
RT9600
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 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.
