MAX17480GTL+T

Overview

The MAX17480GTL+T is a specialized Power Management IC (PMIC) designed for AMD mobile processors. It functions as a three-output, fixed-frequency buck controller supporting the Serial VID Interface (SVI). The device integrates two high-current synchronous step-down switching regulators for CPU core power and one internal switch regulator capable of delivering up to 4A for Northbridge core power. It utilizes a TQFN-40 package.

Feature Summary

• Integrates dual high-current synchronous buck controllers for processor core voltage regulation
• Includes an integrated 4A internal switch regulator for Northbridge power supply
• Supports AMD Serial VID Interface (SVI) for dynamic voltage control

Applications

• AMD mobile CPU core power supply design
• Northbridge core voltage regulation in mobile platforms
• Portable computing systems requiring SVI-compliant power management

Procurement Notes

Verify component authenticity through authorized channels due to discontinuation status. Confirm RoHS compliance documentation matches specific manufacturing lot requirements. Ensure storage conditions adhere to moisture sensitivity level specifications prior to assembly. Validate pinout compatibility with target PCB layout against official datasheet revisions.

Selection Notes

Select this component for designs requiring integrated multi-phase control for AMD SVI architectures. Evaluate thermal performance within the TQFN-40 footprint relative to system airflow constraints. Consider the internal 4A limit for Northbridge loads when sizing external components for other outputs. Verify input voltage range compatibility with system battery profiles.

Part Context

This part belongs to the MAX17480 series of mobile serial VID controllers. It replaces older discrete power solutions by integrating multiple buck stages into a single compact package. The GTL suffix indicates specific tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

No direct public substitute part numbers are confirmed in available documentation. Designers should evaluate newer generations of AMD SVI controllers from Analog Devices for long-term availability.
