Hi all,
This efficiency is under 58%.

My questions are two.
One is that it can be increased more than 60% efficiency?
The other is that are there any other way not using MCU with more than
60% efficiency?
Well - thats kind of impossible to answer without the actual circuit
diagram. Post a picture of this and we might be able to help you
Also what are the conditions. Input voltage - output load?
To increase the efficiency: Use schottky diodes on the output, reduce
core losses of transformer, reduce copper losses of the windings, use a
better output cap to reduce ESR losses, use better RFI filter with less
loss, reduce aux. circuit
consumption,...............................bla bla bla

Klaus
