MAX1917EEE+

Overview

The MAX1917EEE+ is a DC/DC controller designed for DDR memory applications, manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 4.5V to 22V and provides two outputs with adjustable voltages from 0.4V to 5V. The device utilizes current mode control and supports tracking, sinking, sourcing, and synchronization functions. It is housed in a 16-SSOP package (3.90mm width) or 16-QSOP, suitable for surface mount installation. The operational temperature range extends from 0°C to 85°C.

Feature Summary

• Supports DDR memory controller applications with precise voltage regulation
• Enables synchronized multi-phase operation through tracking and synchronization capabilities
• Offers flexible output configuration with independent sinking and sourcing control

Applications

• DDR memory power supply systems
• Multi-voltage rail generation for embedded processors
• Portable computing devices requiring synchronized power sequencing

Procurement Notes

Verify the specific package variant (SSOP vs QSOP) against design requirements, as both are associated with this part number. Confirm that the application strictly adheres to the 4.5V to 22V input range. Ensure thermal management solutions account for the surface mount package constraints within the specified operating temperature limits.

Selection Notes

Select this component when designing power systems for DDR memory interfaces requiring synchronized phase control. The dual-output capability allows for generating multiple voltage rails from a single controller. Consider the current mode control architecture for improved transient response compared to voltage mode alternatives in similar form factors.
