MAX1654EEE

DC DC Switching Controllers Overview

The MAX1654EEE is a high-efficiency, PWM step-down DC-DC switching controller manufactured by Analog Devices Inc./Maxim Integrated. It operates with a fixed switching frequency of 300 kHz and supports an input voltage range suitable for standard bus applications. The device provides two independent regulated outputs, delivering up to 10 A of output current. It features a maximum duty cycle of 99% and regulates output voltages between 2.5 V and 5.5 V. Designed for surface-mount installation, it utilizes a 16-QSOP package and functions reliably within an operating temperature range of -40°C to +85°C.

DC DC Switching Controllers Feature Summary

• High-efficiency PWM step-down topology for power conversion
• Dual-output capability with integrated control circuitry
• Fixed 300 kHz switching frequency for compact external component sizing
• Wide duty cycle range supporting low dropout operation

DC DC Switching Controllers Applications

• Point-of-load regulation in telecommunications equipment
• Power management for industrial control systems
• Voltage conversion for embedded computing modules

DC DC Switching Controllers Procurement Notes

Verify the specific suffix designation when ordering, as variations such as MAX1654EEE+ indicate RoHS-compliant manufacturing. Confirm package availability and lead times directly with authorized distributors, as supply status may vary. Ensure compatibility with existing PCB footprints for the 16-QSOP configuration before procurement.

DC DC Switching Controllers Selection Notes

Select this component for designs requiring dual isolated or non-isolated buck outputs from a single controller. The 300 kHz frequency balances efficiency and passive component size. Verify that the required output current does not exceed the 10 A limit per channel and that the input voltage aligns with the controller's operational specifications.

DC DC Switching Controllers Part Context

This part belongs to the MAX1654 family of switching controllers. It is functionally related to variants like MAX1654EEE+, which share identical electrical characteristics but differ in environmental compliance. The device serves as a core power management solution for multi-rail systems requiring synchronized or independent buck regulation.

DC DC Switching Controllers Replacement Considerations

The MAX1654EEE+ is a direct replacement offering identical functionality with updated material compliance. No other cross-model substitutes are confirmed in public documentation.
