LT1172HVCT#06PBF

Overview

The LT1172HVCT#06PBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It operates at a fixed switching frequency of 100 kHz and supports an input voltage range from 3 V to 60 V. The device provides an adjustable output voltage with a maximum output current capability of 1.25 A. It features a low operating supply current of 6 mA and functions within a temperature range of -40°C to +100°C. The component is housed in a CT package, which corresponds to the TO-220-5 form factor, and is designed for high-efficiency DC-to-DC conversion applications.

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 along with complete oscillator, control, and protection circuitry.
• Capable of handling wide input voltage ranges up to 60 V for versatile power management solutions.

Applications

• Forward converter designs
• Flyback converter implementations
• Buck and boost regulator circuits

Procurement Notes

Verify the specific suffix #06PBF against official Analog Devices documentation to confirm if it denotes a unique packaging or compliance variant distinct from the standard LT1172HVCT#PBF. Ensure the source document explicitly defines this suffix, as generic datasheets may only list the base model number. Cross-reference the manufacturer's ordering guide for accurate part identification.

Selection Notes

Select this component when designing systems requiring a single-chip solution for various DC-DC topologies with input voltages up to 60 V. The integrated switch eliminates the need for external power transistors, simplifying board layout. Consider the TO-220-5 package for thermal management requirements associated with 1.25 A output currents in industrial or automotive environments.
