LT1766EFE-5#TRPBF

Overview

The LT1766EFE-5#TRPBF is a monolithic step-down switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5 V to 60 V and provides a fixed 5 V output at up to 1.2 A. The device integrates a 200 kHz switching frequency, adjustable shutdown control, and features a TSSOP-16 package for surface mount installation.

Feature Summary

• Integrates a high-voltage power switch capable of handling input voltages up to 60 V
• Includes adjustable shutdown functionality for system power management
• Utilizes constant-frequency current mode architecture for stable operation

Applications

• Industrial point-of-load regulation
• Battery-powered systems requiring wide input ranges
• General-purpose DC/DC conversion in compact designs

Procurement Notes

Verify the specific suffix #TRPBF against official documentation to confirm tape-and-reel packaging and lead-free status. Confirm RoHS compliance details directly from the manufacturer datasheet as distributor listings may vary. Ensure the fixed 5 V output variant matches the design requirement, as other voltage options exist within the LT1766 family.

Selection Notes

Select this component when a wide input voltage range up to 60 V is required alongside moderate output current. The fixed 5 V output eliminates external feedback resistor selection. Consider the TSSOP-16 package constraints for thermal performance and board space compared to larger packages or alternative topologies.

Part Context

This part belongs to the LT1766 series of high-voltage buck regulators. It shares architectural similarities with variants like the LT1766EFE-3.3#PBF but differs in output configuration and packaging format. The series is designed for applications needing efficient conversion from higher voltage rails.

Replacement Considerations

LT1766EFE-5#PBF: Identical electrical specifications and fixed 5 V output; differs only in tube packaging instead of tape-and-reel.
