LT3957EUHE#TRPBF

Overview

The LT3957EUHE#TRPBF is a wide input range, current mode DC/DC converter manufactured by Analog Devices Inc. It supports multiple topologies including boost, flyback, SEPIC, and inverting configurations to generate positive or negative output voltages. The device operates with an input voltage range of 3V to 40V and delivers up to 5A of output current. It features a fixed 1MHz switching frequency and includes a shutdown pin for power management. The component is housed in a QFN-36 package and is rated for operation between -40°C and +125°C.

Feature Summary

Supports versatile topology configurations including boost, flyback, SEPIC, and inverting converters.
Capable of generating either positive or negative output voltages from a single input source.
Integrates current mode control architecture for stable regulation across varying load conditions.

Applications

Industrial systems requiring isolated or non-isolated DC/DC conversion
Automotive electronics utilizing wide input voltage ranges
Telecommunications infrastructure power supplies

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing components. Confirm that the EUHE designation corresponds to the specified temperature grade and package variant. Ensure compatibility with the intended PCB footprint for the QFN-36 housing. Validate RoHS compliance status through official manufacturer documentation prior to integration into production assemblies.

Selection Notes

Select this component when designing circuits requiring flexible topology options such as SEPIC or inverting converters. It is suitable for applications needing high output currents up to 5A with a maximum input voltage of 40V. Consider the fixed 1MHz switching frequency for electromagnetic interference planning. Ensure the thermal design accommodates the QFN-36 package constraints for the expected operating environment.

Part Context
