... 6/8 START UP AND SHORT CIRCUIT CONDITIONS trans-conductance sufficient supply for the TSM1013 has to be ensured under any condition. It would then be necessary to add some circuitry to supply the chip compensation with a separate power line. This can be achieved in numerous ways, including an additional winding on the transformer. ...
