Lighting, Ballast Controllers Procurement Notes

Verify component status as the L6585DE is listed as obsolete. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing design constraints before procurement. Check for end-of-life notifications and recommended replacement strategies if long-term supply is required.

Lighting, Ballast Controllers Selection Notes

Select this component for designs requiring integrated PFC and half-bridge control in a single package. It is suitable for universal input voltage operations meeting EN61000-3-2 Class-D harmonic requirements. Consider its transition mode operation for high efficiency and low total harmonic distortion in lighting applications.

Lighting, Ballast Controllers Part Context

The L6585DE belongs to STMicroelectronics' family of ballast control ICs. It is designed to replace discrete solutions by combining PFC and HB functions. This integration reduces component count and simplifies the design of energy-saving lighting drivers. It is often used in reference designs like STEVAL-ILL038V1 and STEVAL-ISA080V1.

Lighting, Ballast Controllers Replacement Considerations

Check for direct pin-to-pin replacements within the same product family. Verify if newer generations offer improved thermal performance or extended availability. Consult official documentation for any functional differences in control algorithms or protection thresholds.
