LT1766EFE#TRPBF

Overview

The LT1766EFE#TRPBF is a monolithic buck switching regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 5.5 V to 60 V and delivers up to 1.2 A of output current. The device features a fixed 200 kHz switching frequency and provides a fixed 5 V output. It is housed in a TSSOP-16 package with exposed pad for surface mount installation. The component supports shutdown functionality and operates at temperatures from 0°C to +125°C, drawing 2.5 mA during operation.

Feature Summary

• Integrates a high-voltage power switch capable of handling inputs up to 60 V
• Provides fixed 5 V output regulation via internal feedback network
• Includes shutdown pin for low-power standby modes

Applications

• Industrial control systems requiring isolated or non-isolated DC-DC conversion
• Automotive electronics operating on 12 V or 24 V bus architectures
• Point-of-load regulation for microprocessors and DSPs

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 source is authorized to guarantee part authenticity and traceability. Check for any recent product change notifications that may affect specifications or availability.

Selection Notes

Select this component when a fixed 5 V output is required from a wide input voltage range up to 60 V. The 200 kHz frequency allows for smaller external passive components compared to lower-frequency alternatives. Consider thermal performance requirements due to the TSSOP-16 package size and potential heat dissipation needs under full load conditions.

Part Context

This part belongs to the LT1766 family of high-voltage step-down switching regulators. It shares core topology with variants like LT1766IFE-5#PBF but differs in packaging format. The series is designed for applications needing efficient power conversion from higher voltage rails to lower logic levels.

Replacement Considerations

LT1766IFE-5#PBF offers identical electrical characteristics in tube packaging.
