Advanced Synchronous Rectified Buck
MOSFET Drivers with Protection Features
The ISL6612 and ISL6613 are high frequency MOSFET
drivers specifically designed to drive upper and lower power
N-Channel MOSFETs in a synchronous rectified buck
converter topology. These drivers combined with HIP63xx or
ISL65xx Multi-Phase Buck PWM controllers and N-Channel
MOSFETs form complete core-voltage regulator solutions for
advanced microprocessors.
The ISL6612 drives the upper gate to 12V, while the lower
gate can be independently driven over a range from 5V to
12V. The ISL6613 drives both upper and lower gates over a
range of 5V to 12V. This drive-voltage provides the flexibility
necessary to optimize applications involving trade-offs
between gate charge and conduction losses.
An advanced adaptive zero shoot-through protection is
integrated to prevent both the upper and lower MOSFETs from
conducting simultaneously and to minimize the dead time.
These products add an overvoltage protection feature
operational before VCC exceeds its turn-on threshold, at which
the PHASE node is connected to the gate of the low side
MOSFET (LGATE). The output voltage of the converter is then
limited by the threshold of the low side MOSFET, which
provides some protection to the microprocessor if the upper
MOSFET(s) is shorted during startup. The over-temperature
protection feature prevents failures resulting from excessive
power dissipation by shutting off the outputs when its junction
temperature exceeds +150°C (typically). The driver resets once
its junction temperature returns to +108°C (typically).
These drivers also feature a three-state PWM input which,
working together with Intersil’s multi-phase PWM controllers,
prevents a negative transient on the output voltage when the
output is shut down. This feature eliminates the Schottky
diode that is used in some systems for protecting the load
from reversed output voltage events.
