The ISL6614 integrates two ISL6613 MOSFET drivers and is specifically designed to drive two independent power channels in a Multi-Phase interleaved 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 ISL6614 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 MOSF
The ISL6614 integrates two MOSFET drivers designed for dual‑channel, multi‑phase buck converter topologies. It provides adjustable gate drive voltages from 5 V to 12 V and includes advanced adaptive zero shoot‑through, over‑voltage, and over‑temperature protection.
Typical applications include core voltage regulators for high‑performance microprocessors and high‑current DC‑DC converters. The device is offered in 14‑lead SOIC and 16‑lead QFN packages, both RoHS‑compliant and Pb‑free options.
