FN4819, Synchronous-Rectified Buck MOSFET Drivers

UGATE (Pin 1) Upper gate drive output.

Connect to gate of high-side power N-Channel MOSFET.

PVCC (Pin 7) For the HIP6601, this pin supplies the upper gate drive bias.

Connect this pin from +12V down to +5V.

For the HIP6603, this pin supplies both the upper and lower gate drive bias.

HIP6601, HIP6603 Data Sheet January 2000 File Number 4819 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.

The HIP6601 drives the lower gate in a synchronous-rect
