Dual Channel Synchronous-Rectified
Buck MOSFET Driver
The HIP6602 is a high frequency, two power channel
MOSFET driver specifically designed to drive four power
N-Channel MOSFETs in a synchronous-rectified buck
converter topology. These drivers combined with a HIP63xx
series of Multi-Phase Buck PWM controller and Intersil’s
UltraFETs® form a complete core voltage regulator solution
for advanced microprocessors.
The HIP6602 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 HIP6602 have the capacity to
efficiently switch power MOSFETs at high frequencies. Each
driver is capable of driving a 3000pF load with a 30ns
propagation delay and 50ns transition time. This device
implements bootstrapping on the upper gates with only a
single external capacitor required for each power channel.
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.
