I have some questions to the design example in datasheet 9.2.2 18-32Vin to 9Vpri and 12Viso following from below thread.
1. 12V is isolated output and 8V is primary output. So for primary output that cannot be no more than one half of the minimum input voltage is still a hard restriction or a just recommendation?
2. Is LM5160A good for customer's use case, 10-28Vin to 5.5Vpri and 15Viso? It looks it breaks the 50% duty rule however it can still run simulation on Webench. Please clarify.
