Texas Non-Isolated PoL Module

I can’t tell the difference between TPSM33615RDNR and TPSM33615FRDNR Texas code.
Do you have any reliable information ?

Please let me know - Thanks

Best regards

Hello,
Welcome to the DigiKey TechForum. See page 3 of the datasheet , part TPSM33615FRDNR is fixed and part TPSM33615RDNR is adjustable and both have different external sync configurations .
