Synchronous-Rectified Buck MOSFET Drivers

The HIP6601 and HIP6603 are high frequency, dual MOSFET drivers specifically designed to drive two power

N-Channel MOSFETs in a synchronous-rectified buck converter topology. These drivers combined with a HIP630x Multi-Phase Buck PWM controller and Intersil UltraFETs™ form a complete core-voltage regulator solution for

advanced microprocessors.
