Procurement Notes

This component is listed as End of Life (EOL) and obsolete. Availability is restricted, and it may not be sold in all regions. Verify current stock status and sourcing channels carefully before procurement planning due to discontinuation status.

Selection Notes

Select this part only if legacy compatibility or specific Flyback topology requirements are necessary. Consider the EOL status when designing new products. Ensure input voltage matches the 17 V specification and verify thermal management for the 400 mW dissipation limit in the SOIC-16 package.

Part Context

The CS1613-FSZR belongs to the Cirrus Logic CS1615 series of LED drivers. It is specifically engineered for high-performance AC-DC conversion in lighting applications. As an obsolete product, it represents earlier generations of integrated DSP-based LED control solutions from Cirrus Logic.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Due to the End of Life status, alternative components must be sourced through independent verification of technical equivalence.
