... ESD protection (HBM) Voltage Reference: Fixed output voltage reference 1.25V 0.5% and 1% Voltage precision DESCRIPTION TSM1014 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) mode. TSM1014 integrates one voltage reference and two operational amplifiers. The voltage reference combined with one operational amplifier makes it an ideal voltage controller ...

... If the primary current limitation is considered not to be precise enough for the application, then a sufficient supply for the TSM1014 has to be ensured under all conditions. For this, it would be necessary to add some circuitry to supply the chip with a separate power line. This can be achieved in a number of ways, including putting an additional winding on the transformer ...
