ISL6277HRZ

Special Purpose Regulators Overview

The ISL6277HRZ is a dual-output switching controller designed for AMD Fusion SVI 2.0 CPU and GPU applications. It operates within an input voltage range of 4.5V to 25V, providing adjustable output voltages from 0.006V to 1.55V. The device utilizes the Robust Ripple Regulator (R3) architecture and is housed in a 48-VFQFN package with exposed pad, measuring 6x6 mm. It supports surface mount installation and functions reliably across a temperature range of -10°C to 100°C.

Special Purpose Regulators Feature Summary

Special Purpose Regulators Procurement Notes

Verify component status as discontinued by Renesas Electronics Corporation. Check Product Change Notifications for label updates or manufacturing site changes. Confirm RoHS3 compliance and moisture sensitivity level 3 requirements during handling. Review datasheet specifications for exact electrical parameters before integration.

Special Purpose Regulators Selection Notes

Select this controller for systems requiring SVI 2.0 compatibility with AMD Fusion processors. Ensure input supply voltage remains between 4.5V and 25V. Verify thermal management capabilities for the 48-QFN package. Consider alternative models if current availability is critical due to end-of-life status.

Special Purpose Regulators Part Context

Part of the ISL6277 series from Renesas, focusing on specialized power management for high-performance computing. Related variants include ISL6277AHRZ and tape-and-reel options like ISL6277HRZ-T. The series targets multi-phase voltage regulation for complex processor architectures.

Special Purpose Regulators Replacement Considerations

ISL6277AHRZ serves as a verified variant within the same family. Other ISL6277 series components may offer similar functionality but require interface and pinout verification.
