Abstract
An over-voltage comparator and shutdown circuit for a power converter, comprising at least a first voltage divider connected between ground and a monitored voltage, the voltage divider including a first resistor and a second resistor, a switch mode regulator connected to a primary switch of the power converter, and a first threshold comparator, wherein a monitored input of the first threshold comparator is connected between the first resistor and the second resistor, an anode of the first threshold comparator is connected to ground, and a cathode of the first threshold comparator is connected to the switch mode regulator, and wherein the monitored voltage is voltage at an end of a primary winding of the power converter. An auxiliary output circuit of the power converter may be provided having a first output providing the monitored voltage and a second output providing power to the switch mode regulator.
