AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix 'P100' confirms the 100 kHz fixed frequency variant, as other suffixes indicate different frequencies. Confirm RoHS compliance status via official documentation. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN), as this series has been subject to discontinuation announcements. Ensure the PDIP-7 through-hole package matches the target PCB footprint requirements.

AC DC Converters, Offline Switchers Selection Notes

Select this component when a fixed 100 kHz switching frequency is required for flyback applications. It is suitable for designs needing a 12 V output rail with moderate current demands. Consider the 7-PDIP package for through-hole assembly processes. Evaluate thermal management needs given the 150°C junction temperature rating. Compare against other NCP1216A variants if different switching frequencies like 65 kHz or 133 kHz are more appropriate for the specific transformer design.
