Capacitor selection for TNY288PG
Posted by: jigisha

Hello,
I am designing smps 5v, 1A dual output with TNY288IC. I am facing problem with my smps that it not not providing more than 500ma of current.
As i read the datasheet of TNY288 that i have to use bigger capacitor (10Uf/16V at pin no 2 and 7) in my design. But i dnt have it right now.
Can i use 10uf, 40v electrolite capacitor in that place.
I dont get ceramic capacitor of that value. Can i use elecrolite capacitor on behalf of that? If yes than please secify direction of mounting.
Thanks in advance.

Hi,
What capacitor do you have on the BP pin right now?
Are you using any capacitor?
Can you send me your PIExpert design file?

Can i get my answer over here?
