LT3973IMSE-5#PBF

Overview

The LT3973IMSE-5#PBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It features an adjustable frequency range from 195kHz to 2.15MHz and accepts input voltages up to 42V. The device delivers a maximum output current of 750mA with a minimum fixed output voltage of 1.21V. It operates within a junction temperature range of -40°C to 125°C and utilizes a 10-WFDFN package with exposed pad for surface mount installation.

Feature Summary

Adjustable switching frequency allows optimization for efficiency or component size
Wide input voltage range supports diverse power supply architectures
Low quiescent current consumption enhances energy efficiency in standby modes

Applications

Automotive electronics systems
Industrial control equipment
General-purpose DC-to-DC conversion

Procurement Notes

Verify the specific suffix '#PBF' indicates lead-free compliance when sourcing. Confirm the 'IMSE' designation corresponds to the industrial temperature grade (-40°C to 125°C) required for your environment. Ensure the 10-WFDFN footprint matches your PCB layout constraints before finalizing procurement orders.

Selection Notes

Select this component when a wide input voltage range up to 42V is required alongside moderate output current capabilities. The adjustable frequency feature is critical for applications needing to avoid specific noise frequencies or optimize passive component sizes. Verify that the industrial temperature rating meets the operational environmental standards of the target system.

Part Context

This part belongs to the LT3973 family of synchronous buck regulators designed for high-efficiency power conversion. The IMSE variant specifically denotes the industrial temperature range and MSOP-10E package style, distinguishing it from military or extended commercial variants within the same functional family.

Replacement Considerations

Direct substitutes include other LT3973 variants such as LT3973EMSE-5#PBF or LT3973HMSE-5#PBF, depending on whether commercial or military temperature grades are acceptable. Cross-brand replacements require careful verification of pin compatibility and electrical specifications.
