Dual Advanced Synchronous Rectified
Buck MOSFET Drivers with Pre-POR OVP
The ISL6614B integrates two ISL6613B MOSFET drivers
and is specifically designed to drive two Channel MOSFETs
in a synchronous rectified buck converter topology. This
driver combined with HIP63xx or ISL65xx Multi-Phase Buck
PWM controllers and N-Channel MOSFETs forms complete
core-voltage regulator solutions for advanced
microprocessors.
The ISL6614B features 7V rising threshold and 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. This driver is
optimized for POL DC/DC Converters for IBA Systems.
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 start-up.
The ISL6614B 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.
