Cannot identify SOIC8 with 7 pins.?
« on: March 20, 2023, 12:16:55 pm »
Hi,
We have a 7 pin SOIC8 ...labelled as follows..

"W163B-33 
N24U002A
PSM23"

Do you know what this might be?...we cannot find on the web.

(Suspect its like a high voltage (eg 300-400Vin) Buck...like the LNK302)

Lots of Chinese PSU chips in that sort of package. LCSC may be a good place to start
