Hello everyone, I am looking for the MPN for the marking code: U32RLJ
I have looked everywhere but unfortunately can’t find anything. It is a 
plug-in power supply from Miele (see pictures) and the IC is 100% 
defective. Due to the defective IC, only 12v instead of approx. 30v is 
available at the plug output.


Maybe someone can help me. I would be very happy about help!

Hi Micha,

could be this device:
AP2281-3WG

I checked https://www.s-manuals.com/smd for 'U3' marking (vertical 
column),which leads me to another table. Check there for the 
corresponding SOT-26 package (https://www.s-manuals.com/smd/u3).

BR
Daniel
