LT3980HMSE#TRPBF

Overview

The LT3980HMSE#TRPBF is a high-voltage synchronous step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 4V to 60V and delivers up to 2A of output current. The device features a fixed internal switching frequency of 1.5MHz, enabling the use of small external components. It includes integrated power MOSFETs for high efficiency across the load range. The component supports adjustable output voltages starting from 0.79V. It is housed in a thermally enhanced 16-lead MSOP package designed for surface-mount applications.

Feature Summary

Integrates high-side and low-side N-channel power MOSFETs for efficient synchronous rectification
Features a fixed 1.5MHz switching frequency to minimize external passive component size
Includes programmable soft-start and cycle-by-cycle current limit protection
Provides thermal shutdown and output overvoltage protection mechanisms

Applications

Point-of-load regulation in industrial equipment
Power supplies for telecommunications infrastructure
Battery-powered systems requiring high input voltage tolerance
Automotive electronics and sensor interfaces

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the HMSE variant corresponds to the specified MSOP-16 EP package type. Ensure compatibility with the required thermal management design due to the surface mount configuration. Check RoHS compliance status against current regulatory requirements for your region before finalizing procurement.

Selection Notes

Select this regulator when input voltages exceed standard 36V limits but remain below 60V. The fixed 1.5MHz frequency is optimal for balancing efficiency and component size. Consider the 2A continuous current capability for moderate load applications. Evaluate the thermal performance in the MSOP package against your PCB copper area constraints.

Part Context

This part belongs to the LT3980 family of high-voltage synchronous buck regulators. It shares architectural similarities with other LT-series power management ICs from Analog Devices. The device complements lower voltage regulators by offering extended input ranges suitable for harsh environments.
