problems with top262
Posted by: raja28chowdhury

i want to make a 12volt 20amp power supply
which translates to 240 watts which is well within limits of top262
power supply 250v ac 5%
i tried in pi expert online and it is not suggesting top262
pi expert is saying
"Based on your input specifications, there are no suitable devices for the specified power."
i don't understand what is the problem is
if I choose 24v 10amp everything is fine and i am able to design
Hi,
I suggest you use the PIXLs design tool (which will show the design as a spreadsheet) to do this design.
We often do not cover designs in PIExpert that could be especially challenging for many designers. For example for a high output current design, even small trace inductances in the layout for the secondary side can change performance significantly. similarly for high power designs, subtle changes in transformer construction can lead to changes in leakage reactance that can affect losses in the snubbers considerably.
PIXls will show you the design in a spreadsheet format which also allows you to see the effects of any design changes you make.
Thanks and Regards,
