Hi Franz,
the current through the voltage divider R11, R17, R21 just charges the capacitor C28. When the UVLO threshold voltage is reached the controller starts switching and will be supplied from the auxiliary winding (BIAS) of the transformer T1…
Part Number: PMP10116 Other Parts Discussed in Thread: LM2596 , Hi,
I have following doubts with respect to this design.
1. Value of DNP: What should be values of DNP resistors and capacitors? Or else to be shorted or to be kept open?
2. 5V Auxiliary…
Amit, hello and thank you for your interest in Texas Instruments. Before we start to look at your query versus our database of designs, can you possibly provide more insight as to the input voltage requirements you're looking for? We're clear on the output…
Part Number: UCC28064A Other Parts Discussed in Thread: PMP10116 , UCC28060 , UCC28063A , Hello,
I have a question about UCC2806X in single stage flyback application.
I would like to know how the IC ends soft start in the application of SLUA625. …
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 Stuart,
The UCC28060 is an older PFC controller, but the application note it still valid. More modern PFCs, such as the UCC28064A can be designed very similarly as an interleaved, single-stage flyback. Also for further info, there is a reference…

Hi Tao_2199,
Thanks for your interest in UCC28063A. I don't have data that is an exact match for your customer requirements on this device. PMP10116 is a 200W interleaved flyback using UCC28063A. There is power factor data down to ~25W on page 4 of…
Lin At 200VAC input the peak AC voltage is 311V, so in order to have a 310VDC output a flyback with a transformer is recommended. One of our PFC boost controllers configured as a flyback like UCC28050 (TM 1 phase) in PMP11155 or UCC28063A (TM 2 phase…
