ISL6594A, ISL6594B

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.
