LT1681ESW#TRPBF

Overview

The LT1681ESW#TRPBF is a synchronous forward controller manufactured by Analog Devices Inc. It operates within an input voltage range of 9V to 72V and supports a maximum output current of 20A. The device functions across an operating temperature range of -40°C to 85°C. It utilizes a compact 20-pin SOIC package for surface mount installation.

Feature Summary

Supports synchronous rectification for improved efficiency in forward converter topologies
Capable of handling high input voltages up to 72V for industrial power applications
Designed for single-output configurations with substantial current drive capabilities

Applications

Industrial power supply systems requiring isolated DC-DC conversion
Telecommunications equipment power distribution modules
Automotive electronics power management units

Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm that the ES variant meets the required temperature grade for your application environment. Ensure compatibility with existing PCB footprints for the 20-SOIC package before finalizing procurement specifications.

Selection Notes

Select this component for designs requiring robust synchronous forward control at higher input voltages. Consider the 20A current capability against load requirements. Evaluate thermal performance within the specified -40°C to 85°C range. Compare against non-synchronous alternatives if efficiency is not the primary constraint.

Part Context

This part belongs to the LT1681 family of switching regulators from Analog Devices. It serves as a dedicated controller rather than a complete integrated regulator, requiring external MOSFETs. The SW suffix denotes the wide-body SOIC package suitable for higher current handling compared to standard narrow packages.
