... Since the current through R2 does not change, I error amplifier. This current is monitored inside the L6561 and when reaches about 37 A the output voltage of the multi- plier is forced to decrease, thus reducing the energy drawn from the mains. If the current exceeds 40 A, the OVP protection is triggered (Dynamic OVP), and the external power transistor is switched off until the current falls approximately below 10 A ...
