Part Number: PMP9730
Tool/software:
Hello all, I am working on load sharing among two distinct flyback power supplies, each rated for nominal 12Vdc output and 3 Adc load (with current limiting at full load)
It is expected that the power supplies…
Part Number: PMP9730 As we design AC to DC converter products. So we have a quires regarding universal AC input, 12V/3A single stage PFC Flyback Reference Design with Synchronous Rectification evaluation board. Please clarify this design support our following…
Part Number: UCC28051 Other Parts Discussed in Thread: PMP9730 , UCC28501 , UCC28811 Hello,
I am referring to the PMP9730 reference design employs the UCC28051. While going through the schematic design I came cross the UCC28051 device and came to know…
Part Number: UCC28051 Other Parts Discussed in Thread: UCC28056 , , PMP9730 Tool/software: Hi,
We are designing a AC-DC converter with PFC for a 50W motor control application. Input is 230V 1ph AC and output is 80V DC. We are looking at implementing…

Hi Nakai-san,
A PFC controller is normally a boost topology. We do have reference designs like PMP9730 which uses a customer transformer to implement a single-stage PFC/Flyback. The UCC28050 was the first in this series and the latest is the UCC28056…
Hi Kazuya,
I took a look at all the reference designs and PMPs with this part number, and I just could find PFC Boost converters and Flybacks power supplies, which this is part is intended to be used for. Please, see attached reference design part numbers…

Without any power factor correction, a flyback converter will not achieve power factor above 0.75. There are a few ways you can improve it though
Passive power factor correction - this article summarizes how you can achieve PFC with inductor…
Hi, WangXin:
Thank you for your suggestion, but I haven't got the PMP9730 demo board on hand.
In fact, I do this for a pre-estimation of those single-stage PFC+flyback application, there is a scheme but not sure it will be put into practice. Due…
