Advanced Synchronous Rectified Buck MOSFET Drivers with Pre-POR OVP

The ISL6612B and ISL6613B 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 ISL6612B drives the upper gate to above rising VCC

POR (7V), while the lower gate can be independently driven

over a range from 5V to 12V. The ISL6613B 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. These drivers are 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 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.
