ISL6613CB

Gate Driver Overview

The ISL6613CB is a half-bridge gate driver IC designed for high-frequency synchronous rectified buck converter topologies. It drives both upper and lower N-channel MOSFET gates with an adjustable voltage range of 5V to 12V, optimizing efficiency by balancing gate charge and conduction losses. The device features a peak output current capability of 2A sourcing and 1.25A sinking, with typical rise and fall times of 26ns and 18ns respectively. It operates within a supply voltage range of 10.8V to 13.2V and supports a maximum bootstrap high-side voltage of 36V. The component is housed in an 8-SOIC-EP package and functions across a temperature range of -40°C to 125°C.

Gate Driver Feature Summary

• Adjustable gate drive voltage from 5V to 12V for optimized efficiency
• Integrated adaptive zero shoot-through protection to minimize dead time
• Pre-POR overvoltage protection connects PHASE node to LGATE during startup
• Three-state PWM input prevents negative transients during shutdown

Gate Driver Applications

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

Gate Driver Procurement Notes

Verify the specific suffix (e.g., CB vs EIB) against official Renesas documentation to confirm exact packaging and RoHS status. Note that certain variants may be marked as obsolete or discontinued; check current availability through authorized distributors. Ensure the selected part number matches the required lead-free or non-RoHS specifications for your manufacturing process.

Gate Driver Selection Notes

Select this driver when designing synchronous buck converters requiring independent control of upper and lower gate voltages between 5V and 12V. It is suitable for applications needing fast switching speeds with minimal dead time and integrated protection against shoot-through and pre-power-on overvoltage conditions.

Gate Driver Part Context

The ISL6613A series complements the ISL6612A, differing primarily in gate drive flexibility. While the ISL6612A fixes the upper gate at 12V, the ISL6613A allows independent adjustment of both gates. This series is intended to work with multi-phase buck PWM controllers like the HIP63xx or ISL65xx to form complete core-voltage regulator solutions.
