LT1956EFE#TRPBF

Overview

The LT1956EFE#TRPBF is a high voltage, monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range from 5.5V to 60V and provides a fixed 5V output. The device integrates a high-efficiency 1.5A power switch, oscillator, control logic, and current-mode architecture for fast transient response. It functions at a fixed 500kHz switching frequency and is housed in a 16-lead TSSOP package with an exposed pad.

Feature Summary

Integrates a high-efficiency 1.5A power switch within a single monolithic die
Utilizes current-mode architecture to ensure rapid transient response and stable loop performance
Supports wide input voltage ranges up to 60V for versatile power supply applications

Applications

Industrial point-of-load regulation
Automotive power distribution systems
Distributed power architectures requiring high voltage step-down conversion

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the fixed 5V output variant matches the system requirements, as other output voltages exist within the LT1956 family.

Selection Notes

Select this component for designs requiring a fixed 5V output from high input voltages up to 60V. The integrated 1.5A switch eliminates external pass transistor requirements. Current-mode control simplifies compensation compared to voltage-mode alternatives. Verify thermal dissipation capabilities of the TSSOP package against expected load currents.

Part Context

This part belongs to the LT1956 series of high-voltage buck regulators. It shares architectural similarities with other members like the LT1956IGN-5 but differs in package type (TSSOP vs. SSOP) and reel configuration. The series is designed for robust performance in noisy environments common in industrial and automotive sectors.
