Abstract
A voltage monitor for a fly-back circuit. The circuit includes a voltage source, a transformer comprising a primary winding electrically coupled to the voltage source and a secondary winding electrically coupled to a load, a diode connected between the secondary winding and the load, a switch electrically coupled to the primary winding and a controller operable to open and close the switch to control energy transfer from the primary winding to the secondary winding. The voltage monitor is connected to a node between the secondary winding and the diode that generates an output signal that is a toggling output when the voltage source is operating above an input voltage threshold and a constant output when the voltage source is operating below the input voltage threshold.
