Synchronous Rectified Buck
MOSFET 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 core­voltage regulator solution for advanced microprocessors.

The HIP6601B drives the lower gate in a synchronous
rectifier to 12V, while the upper gate can be independently
driven over a range from 5V to 12V. The HIP6603B drives
both upper and lower gates over a range of 5V to 12V. This
drive-voltage flexibility provides the advantage of optimizing
applications involving trade-offs between switching losses
and conduction losses. The HIP6604B can be configured as
either a HIP6601B or a HIP6603B.

The output drivers in the HIP6601B, HIP6603B and
HIP6604B have the capacity to efficiently switch power
MOSFETs at frequencies up to 2MHz. Each driver is
capable of driving a 3000pF load with a 30ns propagation
delay and 50ns transition time. These products implement
bootstrapping on the upper gate with only an external
capacitor required. This reduces implementation complexity
and allows the use of higher performance, cost effective,
N-Channel MOSFETs. Adaptive shoot-through protection is
integrated to prevent both MOSF ETs fro m conducting
simultaneously.

Features

• Drives Two N-Channel MOSFETs

• Adaptive Shoot-Through Protection

• Internal Bootstrap Device
