carried out in the Control System, but MOSFET as well as Control Circuit element is on
the Frame, so the circuit operates same for the overheat of MOSFET.
(3-6) Transient Voltage Protection Circuit (OVP)
This Circuit is the circuit that operates the Latch Circuit when the Vin terminal voltage
exceeds 22V (TYP). Basically, this circuit protects Transient Voltage, but the Vin
erminal is supplied from the TRANS Auxiliary Winding, and this voltage is roportional
to the output voltage, so it operates when the secondary side out is transient voltage such
as when Control Circuit is open.
