Hi!
I need help identifying this component - it's the black square IC in the middle. I believe there is written "SAQ 48K D27T" but I cannot find anything on google. I think it might be some dc-dc switching voltage regulator but I am not sure. I've measured voltages (while the circuit was powered from 12V battery) on pads on nearby components as shown in the picture.
If you have a clue what it could be I would be so glad. I spent couple of hours looking for it on internet with no result.

Thank you!

Hello,

The mentioned component is an 15uH SMD inductor

I wasn't quite accurate describing what component I meant. I meant the tiny IC marked as "S1". Between the inductor and capacitor.

edit: I am a newbie here. Is there a way how to edit my original post? I don't see any "edit" button.

 

Hello,

That chip could be a switching regulator.
As there is no datasheet available, it is likely an OEM part.
