Part Number: LM5156 Other Parts Discussed in Thread: PMP40274 Tool/software: Hi,
I currently design LM5156 as flyback citcuit.
And according to EVM circuit I ground FB pin.
But I also need the output OVP function.
So could I just pull-up the…
Part Number: LM51551 Other Parts Discussed in Thread: PMP22800 , PMP40274 Tool/software: Hello, I am trying to build a 12V input 24V/1A output flyback power supply using the LM51551 control chip. The chip has an overvoltage protection feature, but the…
Hello,
Thanks for using the e2e forum. It looks like this design is similar to the reference design https://www.ti.com/tool/PMP40274
Because of this, I do not find any problems within the schematic structure. The accuracy of the input OVP should strongly…
Part Number: TPS40210-Q1 Other Parts Discussed in Thread: TPS40210 Hi TI,
We are currently working on a Flyback converter design using the TPS40210 and would like to understand how the loop Bode plots shown in Figures 5.1 and 5.2 of the application…
Hello Wesly,
The link was supposed to be to a 24V in 5V 6A output fly back design using the TPS40210 in a low voltage flyback.
The correct link is a follows. http://www.ti.com/tool/PMP40274

Hi Aneesh,
I could not find a design that exactly meets your specifications, but I found a few that might get you started.
Vin = 18V to 36V, Output Power ~30W
PMP40274 is a synchronous flyback (5V/6A), but with a transformer redesign you could…
Hi Colbert,
It might be easier to use a design like PMP10506 than redesigning the other reference design. Another good staring point is PMP40274. These designs are designed for the correct output power.
Please let me know if you have any questions…
