HIP6602

Dual Channel Synchronous-Rectified Buck MOSFET Driver

DATASHEET

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.
