Changing output voltage of existing LNK6666E design from 12Volt to 5Volt
Hi, I have perfectly working design of Constant Voltage 12V - 5Amp flyback design in LNK6666E chip with following specs:
Input Voltage range: 190-265V AC
Output Voltage: 12V (constant)
Output Current: 5Amp
Ferrite Core used: EE28 gapped core (AL230 Gap). Brand: Cosmo Ferrites
I would like to know what changes needs to be made so that I can use the same circuit to give 5Volt - 10Amp output?
Another thing I wanted to ask is that there is a limitation in the PIExpert tool where output current higher than 10Amp cannot be entered. However, I would like to design 5Volt(CV) - 20Amp & 5Volt(CV) - 40Amp flyback SMPS as well. Please guide me into the right direction for procuring these designs as well.
Awaiting your earnest reply.
