Advanced Synchronous Rectified Buck
MOSFET Drivers with Protection Features
The ISL6594A and ISL6594B 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 the
ISL6592 Digital Multi-Phase Buck PWM controller and
N-Channel MOSFETs form a complete core-voltage
regulator solution for advanced microprocessors.
The ISL6594A drives the upper gate to 12V, while the lower
gate can be independently driven over a range from 5V to
12V. The ISL6594B 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 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 initial start-up.
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.
