LT3980HMSE#PBF

Overview

The LT3980HMSE#PBF is a monolithic buck switching regulator from Analog Devices. It accepts input voltages up to 58V with 80V transient capability. The device provides an adjustable output voltage ranging from 0.79V to 57.42V and delivers a continuous output current of 2A. It features an adjustable switching frequency between 100kHz and 2.4MHz. The IC operates within a temperature range of -40°C to +125°C and is housed in a 16-lead MSOP package with an exposed pad.

Feature Summary

High input voltage tolerance supporting 58V nominal and 80V transients
Adjustable switching frequency allows optimization for efficiency or component size
Integrated synchronous rectification eliminates external diode requirements

Applications

Industrial control systems requiring high-voltage step-down conversion
Automotive electronics operating under wide input voltage variations
Distributed power architectures in telecommunications infrastructure

Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and RoHS adherence. Confirm the MSOP-EP package variant matches thermal management requirements. Ensure the ordering information aligns with the exact electrical specifications required for the target application design.

Selection Notes

Select this component when high input voltage handling and adjustable frequency are critical. The 2A current rating suits moderate power applications. Consider the thermal performance of the exposed pad package for heat dissipation needs. Verify that the required output voltage range falls within the 0.79V to 57.42V limits.

Part Context

This part belongs to the LT3980 family of high-voltage buck regulators. It shares architectural similarities with other members like the LT3990 but differs in current capacity and specific feature sets. The HMSE designation identifies the specific temperature grade and package configuration within the broader product line.
