LT1766HFE#TRPBF

Overview

The LT1766HFE#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 5.5V to 60V and delivers up to 1.2A output current. The device features a fixed 200kHz switching frequency and supports adjustable output voltages. Packaged in a TSSOP-16 surface-mount format, it functions within a temperature range of -40°C to +140°C. Key electrical parameters include a quiescent supply current of 2.5mA and integrated shutdown capability for power management efficiency.

Feature Summary

• Integrated high-voltage buck topology supporting wide input ranges
• Fixed internal switching frequency for simplified external component selection
• Adjustable output voltage configuration via external feedback network
• Shutdown pin functionality for system power control

Applications

• Industrial control systems requiring isolated or non-isolated DC-DC conversion
• Automotive electronics operating within standard voltage rails
• Battery-powered equipment utilizing step-down regulation
• General-purpose power management in embedded systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the supplier provides valid traceability data. Cross-reference the full part number against the latest Analog Devices datasheet to confirm pinout compatibility and thermal specifications for your specific PCB layout requirements.

Selection Notes

Select this component when a wide input voltage range up to 60V is required alongside moderate output current capabilities. The fixed 200kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the extended industrial temperature range if operating in harsh environments. Verify that the TSSOP-16 package fits your board space constraints and thermal dissipation needs.

Part Context

This part belongs to the LT1766 family of high-voltage switching regulators designed for robust performance in demanding applications. It serves as a compact solution for stepping down higher voltage rails to lower logic or analog supply levels. The series is known for integrating the power switch and control circuitry into a single monolithic IC, reducing design complexity.

Replacement Considerations

Consult Analog Devices documentation for direct replacements. Verify pin-to-pin compatibility and electrical parameter alignment before substitution.
