Hi Yue,
The ACon threshold is internally fixed at 80Vac unfortunately. If you can share your customer's design spec, I can suggest an alternative flyback controller that can meet UVLO of 150V.

Ben,
My customer's case is AC input ,24V5A output for motion control application. They used to use UC2844, but the new requirement is to support a configurable ULVO and up to 150V. Please kindly give your suggestion. thanks.
Ben,
Thanks for the recommendation. is there a ref design close to my customer's design requirement? honestly, they are not good at power design.
Hi Yue,
I couldn't find a reference design that was close to what your customer is looking to do. I would suggest generating a webench design using your customer's requirements. You can generate a design using the webench pane on the right side of this page:http://www.ti.com/product/UCC28704/toolssoftware
