LT1172CSW#TRPBF

Overview

The LT1172CSW#TRPBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3 V to 60 V and provides an adjustable output voltage up to 1.25 A. The device features a fixed switching frequency of 100 kHz and a typical quiescent current of 6 mA. It supports multiple topologies including Buck, Boost, Cuk, Flyback, Forward, and Inverting configurations. The component is housed in a 16-SOIC package and includes an internal shutdown control feature.

Feature Summary

• Integrates a high-current, high-efficiency power switch with complete oscillator, control, and protection circuitry on a single die.
• Capable of operation in all standard switching configurations, including buck, boost, flyback, forward, inverting, and Cuk topologies.
• Includes a dedicated shutdown pin for power management control.

Applications

• High efficiency 5V buck converter circuits
• Positive buck converter designs
• Forward converter applications
• General purpose DC-DC conversion systems

Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging rather than tube packaging when reviewing distributor listings. Confirm RoHS compliance status through official documentation. Ensure the SOIC-16 package matches your PCB footprint requirements. Check for any regional distribution restrictions or limited supply notices associated with this part number before finalizing procurement plans.
