MAX8553EEE

Overview

The MAX8553EEE is a synchronous buck controller manufactured by Analog Devices Inc./Maxim Integrated. It operates with an input voltage range of 4.5 V to 28 V and features a switching frequency of 550 kHz. The device is housed in a 16-pin QSOP package (MO-137AB) and supports surface mount installation. It functions as a DDR regulator IC within the PMIC category.

Feature Summary

• Synchronous buck control architecture
• Integrated shutdown capability

Applications

• DDR voltage regulation
• General-purpose DC-DC conversion

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm the specific suffix designation matches the required package and temperature grade. Review the latest datasheet for any design-in updates or lifecycle status changes prior to finalizing procurement plans.

Selection Notes

Select this component when a synchronous buck topology is required for inputs up to 28 V. Ensure the application demands a fixed 550 kHz switching frequency. Verify that the 16-pin QSOP footprint aligns with the PCB layout constraints and thermal management requirements of the target system.

Part Context

This part belongs to the MAX8553 series, categorized under Switching Controllers and Power Management ICs. It is distinct from other Maxim integrated circuits such as the MAX8563 linear controllers or the MAX8505 single-output buck converters. The device serves as a specialized solution for multi-rail power systems requiring precise voltage regulation.

Replacement Considerations

Public confirmed substitute part numbers are not available.
