MAX17409GTI+T

Overview

The MAX17409GTI+T is a single-phase Quick-PWM GPU controller manufactured by Analog Devices Inc. (formerly Maxim Integrated). Designed for processor power applications, it operates within a supply voltage range of 4.5V to 5.5V and draws a typical supply current of 1.5mA. The device is rated for an operating temperature range from -40°C to +105°C. It utilizes a 28-TQFN package with an exposed pad, suitable for surface mount mounting. This component serves as a dedicated controller for managing high-current loads in graphics processing units.

Feature Summary

• Implements Quick-PWM control architecture for efficient voltage regulation
• Optimized specifically for single-phase GPU power delivery systems
• Supports wide operating temperature ranges for robust performance

Applications

• Graphics Processing Unit (GPU) power management
• Processor core voltage regulation
• Single-phase DC-DC converter control circuits

Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm that the 28-TQFN package dimensions match your PCB footprint requirements. Ensure compatibility with existing thermal management solutions due to the exposed pad design. Check for available replacement parts if long-term supply is required.

Selection Notes

Select this controller when designing single-phase power stages for GPUs or processors requiring Quick-PWM technology. Consider the 4.5V to 5.5V input range and -40°C to +105°C operational limits. Evaluate the 28-TQFN package size against board space constraints. Verify that the 1.5mA supply current fits within system power budgets.

Part Context

This part belongs to the Maxim Integrated line of power management ICs, now under Analog Devices Inc. It is categorized under PMIC controllers for processors. The GTI suffix indicates the specific tape-and-reel packaging variant. It is distinct from multi-phase controllers used in higher-power CPU applications.

Replacement Considerations

As the product status is listed as obsolete, direct substitutes should be identified through official Analog Devices cross-reference tools. No public confirmed substitute part numbers are provided in the source data.
