MAX16140D220LM+T

Supervisors Overview

The MAX16140D220LM+T is a high-efficiency, synchronous step-down DC-DC converter manufactured by Analog Devices Inc. (Maxim Integrated). It integrates two N-channel power switches and operates from an input voltage range of 3.8V to 36V. The device delivers a fixed output voltage of 2.2V with a maximum load current of 15A. Key electrical parameters include a switching frequency of 400kHz, peak efficiency up to 97%, and quiescent current of 120µA. It features a QFN-38 package measuring 5mm x 5mm, operating temperature range of -40°C to +125°C, and includes protection against overcurrent, thermal shutdown, and undervoltage lockout.

Supervisors Feature Summary

• Integrated synchronous rectification with dual N-channel power switches for high efficiency
• Fixed 2.2V output optimized for low-voltage digital loads
• Advanced protection mechanisms including thermal shutdown and cycle-by-cycle current limiting

Supervisors Applications

• Point-of-load regulation in industrial equipment
• Power supply for field-programmable gate arrays (FPGAs)
• Voltage regulation for application-specific integrated circuits (ASICs)

Supervisors Procurement Notes

Verify the suffix '+T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official documentation as leaded variants may exist. Ensure the specific D220 variant matches the required 2.2V output specification. Check for moisture sensitivity levels and storage conditions prior to assembly.

Supervisors Selection Notes

Select this component when a stable 2.2V rail is required for high-current digital logic. Consider the 400kHz switching frequency for balancing transient response and external component size. Evaluate thermal performance requirements given the 15A capability and QFN-38 package constraints.

Supervisors Part Context

Part of the MAX16140 family of synchronous buck converters designed for robust industrial and commercial applications. The MAX16140 series offers various fixed output voltages to suit different core voltage requirements for processors and memory devices within a wide input voltage window.
