WEBENCH® Tools/UCC28C40-Q1: OUT pin no output phenomenon

Glad to hear the issue is resolved.

When you see that some WEBENCH designs are not providing transformer product part numbers, here is what you need to know: The WEBENCH designer algorithm designs the transformer taking into consideration several factors: maximum permissible power loss, maximum number of feasible layers, strands, etc. One or more of these parameters could not be met with your design using available core/bobbin database materials and this is why you receive limited information or no product part number. Try relaxing your design spec in WEBENCH until you see more detailed transformer info appear which will include product part numbers. If you must meet an aggressive design spec that is beyond the limits set by WEBENCH, you will be on your own to design a custom transformer. More details can be found in this e2e thread.

Thanks and good luck with your design,
