The problem consists in the following. Has arrived in repair AC / DC-converter VP-168 of company POWERBOX of manufacture (Germany). In primary AC 220V it is established шим controller UCC35701D an inclusion circuit diagramme differs from traditional (not as in даташите). In Germany developers of the power unit have changed a circuit diagramme. Elements in the scheme (SMD обвязка) UCC35701D are not clear. Please, inform, other examples of inclusion. Variants of circuit diagrammes of inclusion шим controller UCC35701D with instructions of face values of elements in the scheme.

Alexander,
Thanks for your interest in TI. I've contacted an applications engineer to support you here.
Can you please include schematic diagrams of the circuit you are using and a clear description of your problem with any supporting waveforms? Details of your transformer may also be valuable.
I'm afraid your question is very generic now and not clear what the detailed problems are.
Regards,
John

I'm not entirely clear what's being asked for here, but this application note www.ti.com/.../slua077.pdf has some example circuits using the UCC3570 at the end.
Hope this helps.
Thanks
Billy
