Hello,

Which elements need to be replaced at the der-288 scheme, while using in it lnk407 in spite of lnk417? 

Thanks & Regards.

Hi,

LNK407 is a dimmable IC, replace Rpin resistor (R10) to 49.9k ohm and refer to the application note for additional components in order to be more compatible (damping and bleeder) for dimmers.
