Synchronous Rectified BuckMOSFET Drivers

The HIP6601B, HIP6603B and HIP6604B are highfrequency, dual MOSFET drivers specifically designed to
drive two power N-Channel MOSFETs in a synchronous
rectified buck converter topology. These drivers combined
with a HIP63xx or the ISL65xx series of Multi-Phase Buck
PWM controllers and MOSFETs form a complete core-voltage regulator solution for advanced microprocessors.
