Procurement Notes

Verify the obsolete status of this component before integration into new designs. Confirm availability through authorized distributors or secondary markets. Ensure compliance with RoHS directives as specified in the official datasheet. Validate pinout and package dimensions against the 14-SOP specification to prevent assembly errors during procurement and manufacturing.

Selection Notes

Select this component for applications requiring integrated triac dimming in a compact SOP package. Consider the 9V to 20V input range and 30mA output limit when designing the power stage. Evaluate the 125°C maximum operating temperature for thermal management requirements. Compare against similar Infineon CY39C series devices if different pin counts or output configurations are needed.

Part Context

This part belongs to the Infineon CY39C series of LED driver ICs, which are optimized for cost-effective and high-performance lighting solutions.
