... If the primary current limitation is considered not to be precise enough for the application, then a suffi- cient supply for the TSM1012 has to be ensured under any condition. It would then be necessary to add some circuitry to supply the chip with a sepa- rate power line. This can be achieved in numerous ways, including an additional winding on the trans- former ...
