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, Jonard,
Considering the output power around below 40w, you could use the full bridge topology. However, I would like to propose flyback topology. Flyback topology will be more simple and cost competitive. The solution could be UCC28700 family. PMP10344…

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…
