HIP6602A
July 2003
FN4902.2
Dual Channel Synchronous Rectified
Buck MOSFET Driver
The HIP6602A 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. This device is available in either a 14
lead SOIC or a 16 lead QFN package with a PAD to
thermally enhance the package. These drivers combined
with a HIP63xx or ISL65xx series of Multi-Phase Buck PWM
controllers and MOSFETs form a complete core voltage
regulator solution for advanced microprocessors.
The HIP6602A 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 HIP6602A 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.
