Hi,

For the VCC bias voltage souce connection, what's TI's suggestion?

example: voltage divider form HV? independent voltage source? or PFC choke?

Thank you.

Hi Chentsu Chung,

Thanks for your interest in UCC28019A. It is recommended to use an independent, regulated supply for VCC of UCC28019A. Take a look at PMP5327 as an example. It uses UCC2889 to implement a small, regulated bias for UCC28019A:www.ti.com/.../pmp5327.
