How to design a multi outputs flyback with 4 outputs of 12v/0.5a using lt3748?

[@zingraffdocta3776]

a stupid question: i'm using lt8302 for a dc-dc converter. i've set up everything but when i start it up, the lt8302 doesn't switch. there is permanently di input voltage at the switch. how can i make it switch on and off ? that was the case in the simulation but i used the command .tran startup and it worked. what should i do now in reality?
