Hello everybody,
I need the data sheet or atleast pinout of the IC 2003.
The "2003" is printed in bold letters on IC. I could not find its equivalent.

I believe it is the ULN2003... here is the datasheet: https://www.st.com/stonline/books/pdf/docs/5279.pdf

Hope this helps.

Dear deepuj, This is not ULN2003. It is a SMPS IC.

Possibly this: AP2003 datasheet and Application Note, Data Sheet, Circuit, PDF, Pinout | Datasheet Archive.
