Part Number: TL783
Dear Kyle Van Renterghem and support member,
Because I can not reply the previous, I new post.
My customer made board of TL783.My customer make six parallel schematic Fig16 Current-Sinking Regulator.
I have a question.
Is there a way to control device variance by adding external configuration?
Best regard.Bob Lee.
In reply to Mark Sellers:
Dear Mark Sellers,
Thank you very much for reply.
The configuration was described in the attached file.
Could you check attached file?
In reply to Bob Lee62837:
I designed that LED total current is 0.7 A.But I measured 0.71A.
The resistance of TL783 is 10.8Ω,and I considered 0.117 A for each IC.（LED total current is 0.117A x6 = 0.7A）
Even if each current is measured, it changes every time.
Is there a way to control by adding external configuration?
May I ask a question?
Your answer was replied as 1.5% LDO.Where it descript in the data sheet?
The accuracy is covered here. Your application may actually be at the 0.5% accuracy as you are using less than a 5V output. Hope this helps.
I tell my customer your addvice.I will feedback you.
