Part Number: LM5021 Other Parts Discussed in Thread: PMP10215 Hi Team,
We want to use PMP10215 for our product, and we find a question about this circuit, pls. help to explain the function of the below circuit red highlight.

Dear Paul,
Here are the answers to your questions:
1. This power supply can be used at maximum load (200W) for short time, I would say 10min. 30min maximum, then derating or air convection should be applied.
This is because in audio applications…
Part Number: PMP10215 Hello,
I'm trying to analyze the schematics of this PSU, but a section of it puzzles me. I have highlighted the section in the attached image. Can someone explain to me what is happening here, and what the function is?
Thanks…
Hello Kashif,
The PMP10215 doesn't have a high enough supply voltage to provide the specifications you want. If you look at the Output Power vs Supply Voltage figures in the TPA3255 datasheet it will give you a better idea of what would be a suitable…
Hello,
We have a reference design with this part that you can find here: https://www.ti.com/tool/PMP10215
You can also refer to our EVM and EVM User Guide for an example schematic and layout: https://www.ti.com/tool/TPA3255EVM

Thanks, Sam. That makes sense.
Having said that, I just come across the PMP10215 design on your website. Would this be an appropriate solution?
Cheers,
Mark
Part Number: LM5021 Other Parts Discussed in Thread: PMP10215 , , PMP40281 , UCC256402 Hi, TI expert,
Currently need to make a two-tube forward design with 300~1000V input Voltage, 24V output Voltage and 200W output Power.
Suppose LM5021 is the…
Hi Sir, As you suggested me to refer LM5021 to use for two switch topology and ask me to refer PMP10215. But can you see and confirm me because LM5021 is suitable for only one mosfet circuitary as written in datasheet(Ideal for flyback) and In PMP10215…
Karthik,
Since the high and low-side switches are turning on/off at the same time, any single output, general purpose, 8-pin, PWM controller can be used to drive a 2-switch forward converter. For example you might consider a controller from UCC28C5y…
Hello Ahmed,
300W is quite a lot for a flyback topology, even a lot for a single ended forward topology. Would not recommend push pull due to voltage stress at FETs and only half of the winding is used.
A two switch forward or a hard switched half…
