ISL6612CB

Gate Driver Overview

The ISL6612CB is a high-frequency MOSFET driver designed for synchronous rectified buck converter topologies. It features two independent drivers with non-inverting inputs, supporting N-channel MOSFETs. The device operates within a supply voltage range of 10.8V to 13.2V and supports a maximum high-side bootstrap voltage of 36V. Key electrical parameters include peak output currents of 1.25A (sink) and 2A (source), propagation delay of 10ns, rise time of 26ns, and fall time of 18ns. It is available in an 8-SOIC package and functions within a temperature range of 0°C to 125°C.

Gate Driver Feature Summary

• Integrated adaptive zero shoot-through protection minimizes dead time and prevents simultaneous conduction of upper and lower MOSFETs.
• Features pre-power-on reset overvoltage protection that limits output voltage by connecting the phase node to the low-side gate during startup faults.
• Supports three-state PWM input operation to prevent negative output voltage transients when the output is shut down.

Gate Driver Applications

• Core voltage regulators for Intel and AMD microprocessors
• High current DC/DC converters
• High frequency and high efficiency VRM and VRD applications

Confirm specific suffix variations against official Renesas documentation to ensure compatibility with required packaging and temperature grades. Cross-reference datasheet revisions to validate pinout and electrical specifications prior to integration.

Gate Driver Selection Notes

Select this driver for applications requiring precise dead-time control and robust protection against shoot-through events in synchronous buck converters. Ensure the selected variant matches the required operating temperature range and package type. Verify compatibility with multi-phase PWM controllers to utilize the three-state input feature effectively.

Gate Driver Part Context

The ISL6612CB belongs to the ISL6612C series of advanced synchronous rectified buck MOSFET drivers. It is engineered to work in conjunction with HIP63xx or ISL65xx multi-phase buck PWM controllers to form complete core-voltage regulator solutions. The series provides flexibility in optimizing trade-offs between gate charge and conduction losses through adjustable drive voltages.
