                             Synchronous-Rectified Buck MOSFET Drivers
General Description                                            Features
The RT9603 is a high frequency, dual MOSFET drivers            l   Drives Two N-Channel MOSFETs
specifically designed to drive two power N-Channel             l   Adaptive Shoot-Through Protection
MOSFETs in a synchronous-rectified buck converter              l   Supports High Switching Frequency
topology. The device combined with the RT924x series               - Fast Output Rise Time
of multi-phase PWM controllers and MOSFETs form a                  - Propagation Delay 40ns
complete core voltage regulator solution for advanced          l   Tri-State Input for Bridge Shutdown
microprocessors.                                               l   Supply Over-Voltage Protection above Maximum
                                                                   Voltage Rating
The output drivers in the RT9603 can efficiently switch
                                                               l   Supply Under-Voltage Protection
power MOSFETs at frequencies up to 500kHz. It shall be
                                                               l   Upper MOSFET Direct Shorted Protection
taken into account the thermal consideration when the
                                                               l   Small SOP-8 Package
switching frequency above 500kHz. Each driver is
capable of driving a 3nF load in 30/40ns rise/fall time with
fast propagation delay from input transition to the gate of    Applications
the power MOSFET. The device implements boot-
                                                               l   Core Voltage Supplies for Intel Pentium
