Linkswitch-CV LNK626 DCON
I'm trying to design a circuit using Linkswitch-CV LNK626.
When I enter the parameters in PI Expert Online, the message "DCON (Output Diode conduction time) should not be less than 4.5 us." Is displayed.
When I experimented, it was a short time when the load was light.
Also, maximizing the load increased the time. The DCON time changes depending on the load.
The datasheet states that the feedback-pin Sampling Delay time is typically 2.75us.
Does it have to be 4.6us or higher even under a light load?
Or should it be 4.6us or more at maximum load?
When should it be 4.6us?
Also, why is DCON 4.6us?
