Procurement Notes
Verify the manufacturer designation carefully, as this component appears under both IXYS Integrated Circuits and Littelfuse Inc. due to corporate acquisitions. Confirm the specific suffix (e.g., N vs NE) matches your board design requirements. Check current lifecycle status, as some listings indicate end-of-life or obsolescence warnings. Ensure datasheet revisions align with your design specifications before finalizing procurement orders.
Selection Notes
Select this component for designs requiring a cost-effective, high-efficiency solution for driving multiple LEDs in series or parallel. It is suitable for applications needing stable operation at high duty cycles. Consider the SOIC-EP-Wide-8 package for thermal management and space constraints. Verify that the required input voltage range fits within the 8 V to 550 V specification and that PWM dimming compatibility is necessary for the application.
Part Context
This part belongs to the CPC9909 series of offline LED drivers. Originally manufactured by IXYS Integrated Circuits, the product line was integrated into Littelfuse's portfolio. These devices are engineered for high efficiency and low cost, targeting general illumination and specialized lighting markets where reliable off-line operation is critical.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Users should consult official Littelfuse or IXYS catalogs for direct replacements or cross-reference guides.
