LT1956IGN-5#TRPBF

Overview

The LT1956IGN-5#TRPBF is a high-voltage step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5 V to 60 V and delivers a fixed 5 V output at up to 1.2 A. The device integrates a 1.5 A switch and features a 500 kHz switching frequency. Quiescent current is 25 uA, while operating supply current is 2.5 mA. It is housed in a 16-lead SSOP package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates a 1.5 A power switch for high-current buck conversion
• Supports wide input voltage ranges up to 60 V
• Includes internal compensation and soft-start capabilities

Applications

• Industrial control systems
• Distributed power architectures
• High-voltage point-of-load regulation

Procurement Notes

Verify the specific suffix #TRPBF confirms tape-and-reel packaging versus tube variants. Confirm RoHS compliance status through official documentation. Check for obsolescence notices or lifecycle changes from Analog Devices. Ensure the supplier provides valid traceability data for quality assurance protocols.

Selection Notes

Select this component for applications requiring high input voltages and moderate output currents. The fixed 5 V output simplifies design compared to adjustable versions. Verify thermal performance requirements for the SSOP package under maximum load conditions. Consider the 500 kHz frequency for balancing efficiency and component size.

Part Context

This part belongs to the LT1956 family of high-voltage buck regulators. It shares architectural similarities with other LT1956 variants but differs in output voltage configuration and packaging style. The series is designed for robust performance in demanding industrial environments.
