ISL6534CRZ-T

Overview

The ISL6534CRZ-T is a triple voltage regulator IC manufactured by Renesas Electronics Corporation. It integrates two synchronous-rectified buck controllers with 12V gate drivers and one linear controller. The device operates as a dual PWM controller with a maximum switching frequency of 1000kHz. It utilizes voltage-mode control and pulse width modulation techniques. The component is housed in a 32-pin QFN package measuring 5x5 mm.

Feature Summary

• Integrates two synchronous buck controllers with dedicated 12V gate drivers
• Includes an additional linear regulator for auxiliary power needs
• Supports voltage-mode control with adjustable switching frequencies up to 1MHz

Applications

• Multi-rail server power supply systems
• High-performance computing platforms requiring synchronized voltage regulation
• Industrial equipment with complex power distribution requirements

Procurement Notes

Verify the specific suffix 'CRZ-T' against official Renesas documentation to confirm tape-and-reel packaging and RoHS compliance status. Confirm current lifecycle status, as sources indicate this part may be discontinued or obsolete. Ensure compatibility with existing PCB footprints for the 32-QFN package before procurement.

Selection Notes

Select this component when a single IC solution is required to manage multiple voltage rails efficiently. It is suitable for designs needing both high-efficiency synchronous buck conversion and a stable linear output. Verify that the 12V gate driver capability matches the external MOSFET requirements for the intended application load.

Part Context

This part belongs to the ISL6534 family of dual PWM controllers with integrated linear regulators. It is designed for applications requiring compact power management solutions. The series typically targets high-density power supplies where board space is limited and multiple regulated outputs are necessary.

Replacement Considerations

Check for active equivalents from Renesas such as the ISL6534CRZ if the tape-and-reel variant is unavailable. Verify pinout compatibility and electrical specifications before substituting with other dual-buck controllers.
