UCC3583D

Overview

The UCC3583D is a Switch Mode Secondary Side Post Regulator manufactured by Texas Instruments. It is housed in a 14-SOIC package and operates within an industrial temperature range of 0 to 70 °C. The device functions as a switching controller utilizing current-mode control techniques with pulse width modulation. Electrical specifications include a maximum input voltage of 14 V, a minimum input voltage of 8.9 V, and a nominal input voltage of 12 V.

Feature Summary

• Implements secondary side post regulation for switch mode power supplies
• Utilizes current-mode control architecture for precise regulation
• Integrates pulse width modulation technology for efficient switching

Applications

• Secondary side post regulation in isolated power converters
• Switching controller applications requiring current-mode operation
• Power supply designs compatible with 12 V nominal input systems

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm that the component meets all required regulatory standards, including RoHS compliance and lead-free status, prior to integration into the final design.

Selection Notes

Select this component when secondary side post regulation is required for high-efficiency power conversion. Ensure the application supports current-mode control strategies and operates within the specified 8.9 V to 14 V input voltage window. Verify compatibility with the 14-pin SOIC footprint during PCB layout planning.

Part Context

This part belongs to the UCC35xx series of secondary side controllers designed for advanced power management. It serves as a specialized solution for post-regulation tasks in complex power architectures, distinct from primary side controllers or general-purpose operational amplifiers found in other product lines.

Replacement Considerations

Consult the official datasheet for direct pin-to-pin replacements or functional equivalents within the same family. Verify that any substitute maintains identical control modes and input voltage constraints.
