LT1172CT#06PBF

Overview

The LT1172CT#06PBF is a monolithic high-power switching regulator manufactured by Analog Devices. It operates with an input voltage range of 3 V to 60 V and provides an adjustable output voltage up to 65 V. The device supports a maximum switch current of 5 A and features a fixed switching frequency of 100 kHz. It utilizes a TO-220-5 package for through-hole mounting and functions within a junction temperature range of 0°C to 100°C.

Feature Summary

• Supports multiple standard switching topologies including buck, boost, flyback, forward, inverting, and Cuk configurations.
• Integrates a high-current, high-efficiency power switch on the die alongside complete oscillator, control, and protection circuitry.

Applications

• Forward converter designs
• High efficiency constant current chargers
• Negative boost regulator applications

Procurement Notes

Verify availability status as supply may be limited or subject to factory special orders. Confirm that the #06 suffix denotes specific manufacturing or compliance attributes without altering functional performance. Ensure compatibility with existing thermal management solutions for the TO-220-5 package.

Selection Notes
