AC DC Converters, Offline Switchers Procurement Notes

Verify the specific suffix R2G against official onsemi documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status as legacy variants may differ. Check current lifecycle status as older controllers are frequently subject to discontinuation notices. Ensure compatibility with existing PCB footprints before finalizing procurement orders.

AC DC Converters, Offline Switchers Selection Notes

Select this component for designs requiring a fixed 60 kHz switching frequency in compact surface-mount layouts. It is suitable for applications needing integrated protection features without external sensing components. Consider the SOIC-8 package constraints for thermal management. Evaluate if the fixed frequency meets EMI requirements compared to variable frequency alternatives.
