ISL62773HRZ-T

Special Purpose Regulators Overview

The ISL62773HRZ-T is a multi-output switching controller designed for AMD Fusion desktop processors. It complies with the SVI 2.0 interface and utilizes the Robust Ripple Regulator (R3) technology. The device integrates two output channels with an input voltage range of 4.5V to 25V and adjustable output voltages from 0.006V to 1.55V. It operates within a temperature range of -10°C to 100°C and is housed in a 48-QFN (6x6mm) package.

Special Purpose Regulators Feature Summary

• Supports AMD Fusion SVI 2.0 interface for direct CPU/GPU communication
• Integrates Robust Ripple Regulator (R3) control architecture
• Provides dual independent output channels for core power delivery

Special Purpose Regulators Applications

• AMD Fusion desktop microprocessor core power supply
• Desktop graphics processor voltage regulation
• Multi-phase PWM regulator systems for integrated platforms

Special Purpose Regulators Procurement Notes

Verify component authenticity through authorized Renesas distributors or certified partners. Confirm RoHS compliance status and moisture sensitivity level (MSL 3) prior to assembly. Ensure storage conditions adhere to JESD22-A113 standards to prevent humidity damage. Validate that the specific tape-and-reel packaging matches design requirements for automated placement equipment.

Special Purpose Regulators Selection Notes

Select this component for designs requiring strict adherence to AMD SVI 2.0 specifications. The R3 technology offers improved transient response compared to traditional PWM controllers. Consider the 48-pin QFN footprint for space-constrained motherboard layouts. Evaluate thermal performance under maximum load conditions given the 100°C operating limit.

Special Purpose Regulators Part Context

This part belongs to the ISL62773 series, which includes variants like the ISL62773HRZ. The series addresses the power management needs of AMD's Fusion A-series processors. It represents Intersil's contribution to the platform before Renas acquisition. The device serves as a critical PMIC for high-performance computing applications.

Special Purpose Regulators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing board designs if considering alternative vendors. Check for pin-to-pin equivalents only after consulting official Renesas obsolescence notices.
