MAX1809EEE

Overview

The MAX1809EEE is a step-down DC-DC converter designed for DDR memory termination. It operates with an input voltage range of 3V to 5.5V and delivers up to 3A output current. The device features a fixed switching frequency of 1MHz and provides an adjustable output voltage from 1.5V to 2.5V. It utilizes constant-off-time PWM control and supports reversible energy flow. The component is housed in a QSOP-16 package and functions within a temperature range of -40°C to +85°C.

Feature Summary

Supports reversible energy flow for bidirectional power transfer
Utilizes constant-off-time pulse-width modulation control
Integrated shutdown capability for power management

Applications

DDR memory termination supply
Low-voltage step-down regulation
Portable electronic devices requiring efficient power conversion

Procurement Notes

Verify the specific suffix and RoHS compliance status, as availability may vary by region. Confirm that the QSOP-16 package matches your PCB footprint requirements. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.

Selection Notes

Select this component when a compact solution for DDR memory power rails is required. The 1MHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Ensure the input voltage remains within the 3V to 5.5V range to maintain stable operation and efficiency.

Part Context

This part belongs to the Maxim Integrated PMIC family, specifically targeting high-performance memory applications. It serves as a dedicated voltage regulator for double data rate (DDR) technologies, offering a balance of size, efficiency, and transient response suitable for mobile and embedded systems.

Replacement Considerations

Check for direct pin-compatible upgrades within the same series if supply constraints exist. Verify that any substitute maintains the 3A current rating and 1MHz switching frequency to ensure circuit stability without redesigning the power stage.
