We've just received a RDK-611 kit and realized the InnoSwitch pin FWD is connected to the 12-V negative transformer pin instead of the 5-V one, as showed in RDR-611 schematic...
We noticed that so soon because this was the main reason to buy the kit: to verify the minimal positive voltage on the FWD pin (i. e., during the primary mosfet conduction) which allows the InnoSwitch to start-up. So, what is this minimal voltage in fact? And, once started, what is the minimal value to keep the InnoSwitch away from the auto-restart entering? Was this the reason to use the 12-V transformer pin in RDK-611?
This is a special concerning point in our project because it must operate from 36 Vdc primary voltage. Thus, with the most suitable turns ratio options, the FWD pin positive voltage may be too low.
