LT1766IGN#TRPBF

Overview

The LT1766IGN#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 a continuous output current of 1.5A. The device integrates a high-efficiency 1.5A, 0.2Ω power switch and functions at a fixed switching frequency of 200kHz. It utilizes current-mode control for rapid transient response and includes internal compensation. The component is housed in a 16-lead SSOP package and is rated for operation between -40°C and +85°C.

Feature Summary

• Integrates a high-efficiency 1.5A power switch with low on-resistance
• Employs current-mode control architecture for stable loop performance
• Features internal frequency compensation to simplify external design
• Supports wide input voltage ranges suitable for various bus architectures

Applications

• Point-of-load regulation in industrial equipment
• Battery-powered systems requiring efficient step-down conversion
• Telecommunications infrastructure power distribution
• General-purpose DC/DC conversion in embedded systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when reviewing distributor listings. Confirm the manufacturer designation as Analog Devices Inc., formerly Linear Technology, to ensure authenticity. Cross-reference the full part number against official Analog Devices documentation to validate the SSOP-16 package type and temperature range specifications before finalizing procurement orders.

Selection Notes

Select this component for designs requiring a robust 60V input tolerance and 1.5A output capability without external pass transistors. The fixed 200kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the application benefits from current-mode control dynamics and that the thermal characteristics of the SSOP package align with the expected power dissipation levels in the target enclosure.

Part Context

This part belongs to the LT1766 family of monolithic buck regulators designed for high-voltage, high-current applications. The series is characterized by its integrated power switch and simplified external component requirements. The LT1766IGN variant specifically denotes the industrial temperature grade and SSOP packaging, distinguishing it from other pinout or thermal options within the broader product line.
