4. Vcc Terminal,Startup Circuit
Startup is performed by the startup resistor and the condenser between Vcc and S/GND.
The startup voltage, Vcc is 18.2V (typ)and starts the circuit by charging C2 from the startup resistor.
After startup, operation continues with power supplied from the transistor drive winding wire .

5. OCP / OLP
From the transistor design, under medium load with only one bottom left,it is possible for Id to exceed
50%of the normal pseudo oscillation duty.In particular,if there is still a bottom under the maximum load at
VinAC (Min), confirming the condition is required. The following is an explanation of the pseudo
oscillation signal input of the OCP/BD terminal.
