111-3013

Overview

The Infineon Technologies 111-3013 is a DC-DC switching controller IC designed for step-up and step-down power conversion applications. It operates within an 8-SOIC package, providing a compact solution for voltage regulation tasks. The component functions as a positive output regulator controller, supporting both buck and boost topologies to manage power infrastructure efficiently.

Feature Summary

• Supports step-up and step-down voltage conversion architectures
• Integrated positive output regulator control functionality
• Compact surface-mount packaging for space-constrained designs

Applications

• Power management systems in renewable energy infrastructure
• General-purpose DC-DC converter circuits
• Voltage regulation modules requiring buck/boost capabilities

Procurement Notes

Verify the current status of this component, as it is listed as obsolete in official records. Confirm availability through authorized distributors or secondary market suppliers. Ensure compatibility with existing board layouts due to the specific 8-SOIC footprint. Check for lead-free compliance if required by project specifications.

Selection Notes

Select this controller when a dedicated buck/boost solution is needed for moderate power applications. Consider the obsolete status and plan for long-term supply chain risks. Evaluate alternative modern controllers from the same manufacturer family if future production stability is a priority. Verify thermal requirements against the SOIC package limitations.

Part Context

This part belongs to Infineon's broader portfolio of power management integrated circuits, originally developed under International Rectifier before acquisition. It represents a legacy solution for basic DC-DC control needs, often found in older industrial or consumer electronics designs that have since been updated to newer generations of controllers.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, engineers should consult official replacement guides or contact technical support for direct equivalents within the current product line.
