Most likely., the inductor is exceeding it saturation current. That is the point where additional current does not add much magnetic energy, and at that point you will see an increase in lost energy (heat). Try an inductor witrh the same inductance, and a higher Isat rating.
My experience with any sort of switching converter is that they work great at low loads, and as you increase the load you see more problems. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
