And guess what - it is usually not the FET that heats up - it is the transformer ... fried several of them and those smell VERY bad ;)
In my experience from watching more naiive colleagues, its always the transistor that blows ! - they assume that the inductor can't saturate: it does: current goes through the roof, because it has a very low resistance:poof - the magic leaks out. Then they may learn more about inductor design. Steve |
