Dual Advanced Synchronous Rectified
Buck MOSFET Drivers with Pre-POR OVP
The ISL6614A integrates two ISL6613A MOSFET drivers and
is specifically designed to drive two 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 ISL6614A drives both the upper and lower gates
simultaneously over a range from 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 ISL6614A also features 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.
