Part Number: PMP10116 Other Parts Discussed in Thread: UCC28063A , Hi team,
I have a customer that is testing reference design PMP10116, which uses UCC28063A. Unfortunately it isn’t working in a stable manner when the output voltage is adjusted.
Their…
Hi David:
there is no a pin special designed or showed PFC ok signal for downstream PWM controller, I would suggest you can add external circuit by sampling PFC bus voltage through Vsense pin and compare with a reference votlage with a comparator or…
Hi Rock,
UCC28064A can support interleaved flyback. We don't have a reference design with UCC28064A for interleaved flyback but we have reference designs of the previous gen UCC28063A for interleaved flyback: https://www.ti.com/tool/PMP10116

Hi Wei-Hao,
No model currently exists for UCC28061 unfortunately. A similar device, UCC28063A, has spice model available. UCC28063A is also an interleaved transition mode PFC controller. This device is also pin to pin compatible with UCC28061. Would…
