LT3481IMSE

Overview

The LT3481IMSE is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an adjustable frequency range from 300kHz to 2.8MHz and accepts input voltages up to 34V, with a maximum rating of 36V. The device provides a positive adjustable output voltage starting at 1.265V and delivers up to 2A of output current. It features a low quiescent current of 50µA. The component is housed in a 10-TFSOP package with an exposed pad.

Feature Summary

Adjustable switching frequency allows optimization for size and efficiency
Low quiescent current enhances efficiency in battery-powered applications
Wide input voltage range supports various power supply sources

Applications

Portable equipment requiring efficient step-down conversion
Battery-powered systems needing low standby current
General-purpose DC-DC conversion in industrial electronics

Procurement Notes

Verify the exact part number suffix, as LT3481IMSE#PBF indicates lead-free tape and reel or tube packaging depending on specific distributor listings. Confirm lifecycle status, as some sources indicate this model may be obsolete. Ensure compatibility with your PCB footprint for the 10-TFSOP package with exposed pad before ordering.

Selection Notes

Select this component when a wide input voltage range up to 36V is required alongside high efficiency at light loads. The adjustable frequency feature permits trade-offs between external component size and noise spectrum. Consider the 2A current limit for moderate power applications where thermal management via the exposed pad is feasible.

Part Context

This part belongs to the LT3481 family of synchronous buck regulators. It is designed for applications demanding high efficiency across a broad load range. The IMSE designation specifies the MSOP/TSSOP package variant within the broader LT3481 product line offered by Analog Devices.

Replacement Considerations

Check for direct pin-compatible alternatives from Analog Devices or other manufacturers if availability is constrained due to obsolescence. Verify that substitute parts maintain the 36V input rating and 2A output capability.
