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-rectifier
bridge to 12V, while the upper gate can be independently
driven over a range from 5V to 12V. The HIP6603 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 output drivers in the HIP6601 and HIP6603 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. Both
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.
