Dual Channel Synchronous Rectified
Buck MOSFET Driver
The HIP6602B 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 HIP6602B 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 HIP6602B 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 a single
external capacitor and resistor 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.
