MAX16003ETE+T

Supervisors Overview

The MAX16003ETE+T is a high-efficiency, synchronous step-down DC-DC converter from Analog Devices. It integrates two N-channel power MOSFETs and operates with an input voltage range of 2.7V to 5.5V. The device delivers up to 3A of output current with a fixed switching frequency of 1.5MHz. It features adjustable output voltage via external resistors and includes comprehensive protection mechanisms such as overcurrent, thermal shutdown, and soft-start functionality for reliable operation in space-constrained applications.

Supervisors Feature Summary

• Synchronous rectification architecture ensures high efficiency across load ranges
• Integrated power switches minimize external component count and board space
• Fixed 1.5MHz switching frequency allows use of small passive components
• Built-in protection against overcurrent, overheating, and inrush current

Supervisors Applications

• Portable electronics requiring efficient power management
• Battery-powered devices with single-cell lithium-ion inputs
• Embedded systems needing stable low-voltage rails
• Industrial control modules with limited PCB area

Supervisors Procurement Notes

Verify the exact suffix 'ETE+T' matches the tape-and-reel packaging specification. Confirm RoHS compliance status through official documentation. Ensure the ordering part number aligns with the intended temperature grade and package type before procurement.

Supervisors Selection Notes

Select this component when input voltages remain between 2.7V and 5.5V and output currents up to 3A are required. Consider the 1.5MHz frequency for smaller inductor sizes compared to lower-frequency alternatives. Evaluate thermal performance based on expected ambient conditions and PCB copper area available for heat dissipation.

Supervisors Part Context

This part belongs to Maxim Integrated's family of synchronous buck converters designed for portable applications. It replaces older non-synchronous designs by improving efficiency and reducing external component requirements. The device supports various output voltages through resistor programming, offering flexibility in system design.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the same product line. Verify that alternative parts support identical input voltage ranges and current capabilities. Ensure switching frequencies match if EMI filtering constraints exist.
