LT1171CT#06PBF

Overview

The LT1171CT#06PBF is a monolithic high-power switching regulator manufactured by Analog Devices Inc. It operates with an input voltage range of 3V to 60V and provides an output current capability of 2.5A, supporting up to 100W of output power. The device integrates a high-current, high-efficiency switch along with all necessary oscillator, control, and protection circuitry on the die. It supports standard switching configurations including buck, boost, flyback, forward, inverting, and Cuk topologies.

Feature Summary

• Integrates a high-current, high-efficiency power switch with complete oscillator, control, and protection circuitry on a single die
• Supports operation in all standard switching configurations including buck, boost, flyback, forward, inverting, and Cuk topologies
• Features external current limiting capability for precise load management

Applications

• Buck converter circuits
• Boost converter circuits
• Flyback converter designs
• Forward converter applications
• Inverting and Cuk topology implementations

Procurement Notes

Verify the specific suffix #06PBF against official Analog Devices documentation to confirm package type and temperature grade specifications. Ensure compatibility with required thermal management solutions given the TO-220 package form factor. Confirm that the external current limiter configuration aligns with system safety requirements before finalizing procurement.

Selection Notes

Select this component when a versatile, high-power switching regulator capable of multiple topologies is required. The integrated switch simplifies design by reducing external component count. Consider the 3V to 60V input range for broad supply compatibility. Evaluate thermal performance requirements due to the 100W power handling capability and ensure adequate heatsinking for the TO-220 package.

Part Context

The LT1171 series belongs to Analog Devices' family of high-power switching regulators. These devices are designed for applications requiring flexible topology support and robust power handling. The CT variant typically denotes a commercial temperature grade, while the #06PBF suffix indicates lead-free packaging compliance. This part serves as a core building block for various DC-DC conversion needs.
