Part Number: UCC28730EVM-552 Other Parts Discussed in Thread: UCC28730 Hello,
Our customer is annoyed the standby power consumption difference with Figure 6 in User's guide SLUUB75. He could measure 680mW at 100VAC no load condition whereas we can see…
Part Number: UCC28730EVM-552 Other Parts Discussed in Thread: UCC28730 , UCC24610 , CSD18534Q5A , UCC24612 Hi,
We have modified the EVM to create a 12V/4W AC/DC power supply. (see excell file)
For the Vs measure we have: 127k (R2) / 59k (R3)
For the Vcs measure…
Part Number: UCC28730EVM-552 Hi,
I just burned my second EVM.
Can someone explain to me why i shouldn't put an isolated differential high voltage probe on the gate signal of the transistor. (It is roasting all the CS resistors (R9 R11 R12) making very…

Other Parts Discussed in Thread: UCC28730EVM-552 Hi
I received an UCC28730EVM-552, and it runs well.
I'm trying to design a AC/DC(5V,2A). I will use this EVM circuit as reference.
But, My AC Input has 3 lines. (L, N, FG). This EVM can connect only…
Hello,
The e2e is on line support. So if you can send it I will not be able to review it. However, you can compare it to the UCC28730 evaluation module schematic to see if there is anything different from your design compared to the evaluation module…
Hi, Ken:
Since the MLCC is sensitive to DC bias, the capacitance reduces a lot as DC bias increased. Thus, the effective capacitance would be less as it shows. For example, MLCC would decrease almost 80% of capacitance as 5VDC. The DC bias characteristic…
Part Number: PMP9561 Other Parts Discussed in Thread: UCC28730EVM-552 , , PMP UCC28730EVM-552 and PMP9561 seem to be the same design - is the Altium source available to save me the effort of re-entering it for a customer design?
Thanks!
Hello Antonio,
Thank you for your interest in the UCC28730 flyback controller.
Although the PMP9009 reference design does not meet all of the customer specs, it is still useful as a reference of how the design will look. Its parameters can be adjusted…
