Synchronous Rectified Buck MOSFET
Drivers

The HIP6601A, HIP6603A and HIP6604 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 HIP63xx
or an ISL65xx Multi-Phase Buck PWM controller form a
complete core-voltage regulator solution for advanced
microprocessors.

The HIP6601A 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 HIP6603A 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 HIP6604 can be configured as
either a HIP6601A or a HIP6603A.

The output drivers in the HIP6601A, HIP6603A and HIP6604
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 MOSFETs from conducting simultaneously.
