RT9603 - Richiek

RT9603 Synchronous-Rectified Buck MOSFET Drivers

The RT9603 is a high frequency, dual MOSFET drivers specifically designed to drive two power N-Channel MOSFETs in a synchronous-rectified buck converter topology. The device combined with the RT924x series of multi-phase PWM controllers and MOSFETs form a complete core voltage regulator solution for advanced microprocessors. The output drivers in the RT9603 .
