Flyback converter can be used to create multiple output using multiple secondary transformers. I am wondering how is the regulation maintained....for eg.....if we have 5V, 3V3, 1V8 and 1V5 as output from 50V input. If the load changes on one of the output...does this not effect the other rail....I don't understand how the controller maintains the reulation on all the rails if load on all rails is changing....or is there a clever idea I might me missing?
