LT1766IFE-5#TRPBF

Overview

The LT1766IFE-5#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 provides a fixed output voltage of 5 V with a maximum output current of 1.2 A. The device features a fixed switching frequency of 200 kHz and includes a shutdown function. It is housed in a TSSOP-16 package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Integrated high-voltage power switch for step-down conversion
• Fixed internal switching frequency reduces external component count
• Shutdown pin enables low quiescent current standby mode

Applications

• Industrial control systems
• Battery-powered equipment
• Distributed power architectures

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging and lead-free compliance. Confirm the manufacturer is Analog Devices Inc. or Linear Technology. Ensure the part number matches the exact electrical specifications required for your design, as variations exist within the LT1766 family.

Selection Notes

Select this component when a fixed 5 V output is required from a high-voltage input source up to 60 V. The fixed 200 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance of the TSSOP-16 package for your specific power dissipation requirements.

Part Context

This part belongs to the LT1766 series of high-voltage step-down switching regulators. It is designed to replace linear regulators in high-input voltage applications to improve efficiency. The series offers both adjustable and fixed output voltage options in various packages.
