AC DC Converters, Offline Switchers Procurement Notes

Verify component status carefully as this part is officially listed as End-of-Life (EOL) by onsemi. Confirm availability through authorized distributors or secondary markets if sourcing is required. Ensure compliance with RoHS3 specifications and check for any relevant Product Change Notices (PCN) regarding manufacturing site or material changes prior to integration.

AC DC Converters, Offline Switchers Selection Notes

Select this component for low-power flyback designs requiring integrated control and switching capabilities. Consider the 8-DIP package for through-hole mounting requirements. Evaluate thermal management needs given the 125°C maximum junction temperature rating. Verify that the 700V breakdown voltage aligns with the input voltage stress conditions of the target application circuit.

AC DC Converters, Offline Switchers Part Context

The FSL117MRIN belongs to the Fairchild Power Switch (FPS™) family, which combines a power MOSFET and controller into a single IC. This series targets cost-effective, high-reliability AC/DC converter designs. The specific model utilizes a standard 8-DIP package suitable for general-purpose industrial and consumer electronics power supplies.

AC DC Converters, Offline Switchers Replacement Considerations

As the FSL117MRIN is discontinued, engineers must identify compatible alternatives from the same FPS™ family or other flyback controllers with similar pinouts and electrical characteristics. Verify that substitute parts meet the 700V breakdown and 15W power requirements.
