Part Number: PMP10344 Hi
I would like to know the purpose of this part of the circuit, in PMP10344:
And how can I shrink the Power Supply size, if possible. Regards.

Part Number: PMP10344 Hi,
I'm having a large ripple in output voltage when mosfet turns off. It's about 2V. I would like to know if it's normal.
The image below shows it. In blue is the gate voltage, and in yellow is the output voltage. The…
Part Number: PMP10344 Hi everyone.
I made a power supply based on PMP10344 with voltage and current adjustments and a new transformer. Now i'm having issues starting up the power supply, it's suposedly to start at around 90V, but in reality it only starts…

Hi,
I would to know if it's possible to change the initial stage of this design to use as a AC/DC three-phase+neutral input.
I imagine that the initial stage of the circuit would be something…

L4 and C3 in PMP10344 are part of the input EMI filter.
I recommend to confirm if the BJT FET is also failed. What could be occurring is that the BJT is failing, which causes a voltage over stress to be applied to UCC28722. If this is the…
Part Number: UCC28700 Other Parts Discussed in Thread: PMP10344 Hi I made a design by using UCC28700 to make a 12VDC 0.5A output power supply from 120-480VAC input range. Could you help review for me?
Thanks,

Hi Wei-Hao,
Thank you very much for your help. Please review attached schematic and check if our design has some potential problems.
We use this PMP10344 to generate 36V/0.7A output.
Thanks again and best regards

Other Parts Discussed in Thread: UCC28700 Hello TI team,
I have building a fly back regulator with the UCC28700 few months ago. With our first samples I had no problems. Now we have produced 60 items and now we have startup problems (starting again and…
