MAX8538EEI+T

Overview

The MAX8538EEI+T is a dual synchronous buck controller manufactured by Analog Devices Inc. under the Maxim Integrated brand, housed in a 28-pin QSOP package. It operates with a switching frequency range of 150 kHz to 1.2 MHz and supports output voltages down to 1.1 V. The device features integrated linear regulators for biasing and includes soft-start and soft-shutdown capabilities. Designed for high-efficiency power management, it is suitable for load point applications, voltage tracking, and DDR memory power supplies.

Feature Summary

• Dual synchronous buck controller architecture
• Integrated soft-start and soft-shutdown functions
• Internal linear regulator for operational biasing

Applications

• Load point power regulation
• Voltage tracking systems
• DDR memory power supply

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status and check current availability as stock levels fluctuate. Ensure the specific suffix matches project requirements before ordering.

Selection Notes

Select this component for designs requiring dual independent buck outputs from a single controller IC. Evaluate thermal performance based on the QSOP-28 package limitations. Verify that the required switching frequency falls within the specified 150 kHz to 1.2 MHz range for optimal efficiency.

Part Context

This part belongs to the MAX8538 series of power management integrated circuits. It is designed to replace older discrete solutions or single-channel controllers in compact multi-rail power architectures. The device integrates control logic and gate drivers to minimize external component count.

Replacement Considerations

Consult official documentation for direct pin-to-pin substitutes. Verify electrical compatibility and thermal characteristics when considering alternative dual buck controllers from other manufacturers.
