... VIPer53EDIP - E / VIPer53ESP - E 5 Secondary Feedback Configuration Example The secondary feedback is implemented through an optocoupler driven by a programmable zener diode (TL431 type) as shown in The optocoupler is connected in parallel with the compensation network on the COMP pin which delivers a constant biasing current of 0.6mA to the optotransistor. This current does not depend on the compensation voltage, and so it does not depend on the output load either ...

... VIPer53EDIP - E / VIPer53ESP - E 9 Short-Circuit and Overload Protection A V threshold of about 4.4V has been implemented on the COMP pin. When V COMPovl goes above this level, the capacitor connected on the TOVL pin begins to charge. When reaching typically V switching. This state is latched because of to the regulation loop which maintains the COMP ...
