MAX1917EEE-T

Overview

The MAX1917EEE-T is a dual-output synchronous step-down DC-DC converter designed for DDR memory power applications. It operates with an input voltage range of 4.5V to 22V and provides two adjustable output voltages between 0.4V and 5V. The device supports a switching frequency of 1 MHz and delivers up to 25A of output current. It functions within an operating temperature range of -40°C to 85°C and is housed in a 16-SSOP surface-mount package.

Feature Summary

• Dual-output architecture optimized for simultaneous DDR core and I/O power supply requirements
• Synchronous rectification design ensures high efficiency across the load range
• Integrated control loop simplifies implementation for memory controller applications

Applications

• DDR memory subsystem power management
• Mobile phone baseband power supplies
• Portable computing devices requiring low-profile regulation

Procurement Notes

Verify the specific suffix (EEE-T) against the manufacturer's official datasheet to confirm pinout, thermal characteristics, and tape-and-reel packaging specifications. Ensure the component meets the required automotive or industrial temperature grades if applicable to your system design. Cross-reference the ordering number with Analog Devices documentation to avoid confusion with non-tape versions.

Selection Notes

Select this component when designing systems that require independent regulation for DDR memory cores and I/O rails from a single input source. The 1 MHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Verify that the 25A current capability aligns with the peak transient demands of the target memory interface.

Part Context

This part belongs to the Maxim Integrated DDR power solution family, specifically engineered to meet the stringent transient response and ripple requirements of modern memory interfaces. It integrates the necessary drivers and control logic to replace discrete MOSFET solutions, reducing board space and assembly complexity for consumer electronics manufacturers.

Replacement Considerations

Consult Analog Devices official substitution guides for direct pin-compatible alternatives. Verify that any replacement maintains the same 16-SSOP footprint and electrical parameters to ensure compatibility with existing PCB layouts without redesign.
