Technical Guide

Once V IN terminal pin 4 voltage reaches approximately 16V, IC801 begins to operate and drive the internal power MOSFET, causing current to flow through the drain/source terminals at pins 3 and 2, and to the winding B1-B2 of switching transformer T802 viaL803andR809.

tovis power supply

After a predetermined length of time to allow the PTC to reach its maximum resistance (but with no actual sensing involved) IC801 says "enough already" and removes the base voltage from transistor Q102, de-energizing the relay and removing power from the de-gaussing coil.
