Procurement Notes
Verify the specific ordering suffix against the manufacturer's official website, as Fairchild part numbers containing underscores may have been converted to dashes during integration into ON Semiconductor’s system. Confirm that the updated nomenclature matches the required procurement specifications before placing orders to ensure compatibility with existing design files.
Selection Notes
Select this component for high-voltage AC offline applications requiring multiple isolated or non-isolated LED strings. Ensure the design accommodates the 8-SOIC-EP thermal requirements due to the exposed pad. Verify that the external circuitry supports the specified dimming protocols and that the input voltage range aligns with the target regional mains supply standards.
Part Context
This device belongs to the LED driver family manufactured by ON Semiconductor. It was originally part of the Fairchild Semiconductor portfolio prior to corporate integration. The product line focuses on efficient power management solutions for lighting applications, utilizing advanced control techniques to maintain stable LED current across varying line conditions.
Replacement Considerations
Consult the official ON Semiconductor documentation for updated part numbers resulting from the Fairchild integration. Verify pinout and electrical parameter compatibility if considering cross-manufacturer alternatives.
