i was designed one smps with 18V/2.5A output,but getting output voltage of 36V-37V.please guide me with proper solution.used ic is TOP248YN.
Dear sir,
I am using LNK6667E for the 12v 5amp smps. Its have the output problems. I make the 5nos smps by attached schmatic whenever one smps is working and 4 giving the zero output. I am not to understand problem.

Hello Sir,
I have designed a 12V-5A SMPS using TOP249 YN IC. Its a universal input design.
but its short circuit protection is not working. When I connect to the VARIAC, up to 100VAC its working
when i increases the input voltage, and then tryining to test for short circuit protection, its not working and
IC burns.
Can you plz provide me the solution.
Thank You
