Hello,

Please note that the outputs of A through F are logic level outputs and are not gate driver outputs. So if you are trying to drive FETs directly this might be your issue.

It might be in your best interest to review the evaluation module (EVM) design and waveforms; as well as, the EVM schematic. https://www.ti.com/lit/pdf/sluub02 You can also order the EVM to evaluate as well.

There is also a Webench design tool that you can use to check your design that you can find at the following link. https://www.ti.com/product/UCC28950?keyMatch=UCC28950&tisearch=search-everything&usecase=GPN#design-development

To get a better understanding of how to design with the UCC28950 it may be worth while reviewing the following design application note. https://www.ti.com/lit/pdf/slua560
