LT3980EMSE#TRPBF

Overview

The LT3980EMSE#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It accepts input voltages up to 58V with 80V transient tolerance and delivers an adjustable output voltage ranging from 0.79V to 57.42V at a maximum current of 2A. The device features an adjustable switching frequency between 100kHz and 2.4MHz, enabling optimization for efficiency or component size. It operates within a junction temperature range of -40°C to 125°C and utilizes a 14-WFDFN package with an exposed pad.

Feature Summary

Supports high input voltages up to 58V with robust 80V transient handling capability
Features adjustable switching frequency from 100kHz to 2.4MHz for design flexibility
Delivers up to 2A output current with adjustable output voltage down to 0.79V

Applications

Industrial control systems requiring high-voltage step-down conversion
Distributed power architectures in telecommunications equipment
Battery-powered devices with wide input voltage ranges

Procurement Notes

Verify the specific suffix TRPBF indicates tape-and-reel packaging when ordering. Confirm the 14-WFDFN package dimensions match your PCB footprint requirements. Ensure thermal management strategies account for the exposed pad design to maintain reliability within the specified operating temperature range.

Selection Notes

Select this component for applications requiring high input voltage tolerance without external clamping circuits. The adjustable frequency feature allows designers to optimize the trade-off between electromagnetic interference and passive component size. Verify that the required output current does not exceed the 2A limit under all operating conditions.

Part Context

This part belongs to the LT3980 family of high-voltage buck regulators. It shares core architecture with other members but differs in packaging and reel configuration. The EMSE designation specifies the MSOP-style DFN package, while TRPBF denotes the specific reel quantity and lead-free finish compliant with RoHS standards.
