LT3980IMSE#PBF

Overview

The LT3980IMSE#PBF is a high voltage, non-synchronous buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 3.6V to 58V and delivers up to 2A of output current. The device features an adjustable output voltage ranging from 0.79V to 57.42V. It supports a programmable switching frequency between 225kHz and 2.25MHz. The component is housed in a 14-WFDFN package with an exposed pad and is rated for operation at junction temperatures from -40°C to 125°C.

Feature Summary

• Supports wide input voltage ranges suitable for industrial applications
• Provides adjustable output voltage control via external resistors
• Features programmable switching frequency for optimization

Applications

• Industrial power supplies
• Distributed power systems
• Point-of-load regulation

Procurement Notes

Verify the specific suffix against official documentation to confirm temperature grade and packaging details. Ensure compatibility with required input voltages and thermal management solutions. Confirm RoHS compliance status through manufacturer declarations before integration into final assemblies.

Selection Notes

Select this component when high input voltage tolerance and moderate output current are required. Consider the non-synchronous topology for cost-sensitive designs where efficiency requirements are less stringent than synchronous alternatives. Evaluate thermal performance based on the selected switching frequency and load conditions.

Part Context

This part belongs to the LT3980 family of high voltage buck regulators. It shares core architecture with other variants but differs in package type and temperature rating. The IMSE designation indicates a specific industrial temperature grade and MSOP-style footprint adaptation within the DFN family context.
