Part Number: LM5156 Tool/software: Dear Specialists,
My customer is considering the same concept with related thread.
Is LM5156 possible to use input(DC12V、DC24V、DC48V、AC85-264V) and output (+/-15V 0.1A)
If yes, could you please provide the reference…
Part Number: LM5156 Other Parts Discussed in Thread: TL431 Tool/software: Hi Team,
may we know of any issue with this schematic? could help double check it for us?
after we checked, there seem to be no problem, thanks for your help and learn from you…
Hi marsh,
m marsh said: The LM5156 appears to be struggling again to provide the desired power.
How does the LM5156 behave? Is the output voltage dropping?
Can you please send some scopeshots? I would like to see Vin, Vout, switchnode and CS in one scopeshot…

Hi Mortiz,
I am revisiting for help.
I have run the Pspice for TI using flyback for 900V input using case. And found 2 abnormal waveforms. Can you kindly provide your professional help?
1, Why red box here, will have a sharp rising of output, before SS…
Hi Moritz,
I did what you suggested: without changing inductor, I replaced mosfet with 100V/40A one. The result was that I got 56V (as it should be) without any problems, and everything is working perfectly. Yes, there are some things to be trimmed, to…
Part Number: LM5156-Q1 Other Parts Discussed in Thread: TL431 , PMP10666 , LM5156 Tool/software: Dear TI Support Team,
I’m designing a flyback converter that outputs ±150V +-60mA, and while the overall circuit functions well in simulations, I’m having trouble…
Part Number: LM5156-Q1 Other Parts Discussed in Thread: LM5156 , LM5157 Tool/software: Hi Teams,
Do we have PSR calculator for LM5156-Q1?
What's the difference between PSR & Non-isolated? If I want to calculate the compensation specs, can I directly use…
Part Number: LM5156-Q1 Tool/software: Hi Team,
Can LM5156-Q1 achieve the I/O condition? I tried to use excel file and webench, but the result shows the condition would be unstable.
12Vin to 120Vout@1A
Do you have any other recommended solution?

Hello Technical Support,
For designed and manufactured DC To DC up converter 10.5v to 28v:
Tested 90 MHz/ 2v ripple at output and Gate FET transistor.
Is there a way to debug or fix such significant ripple ?
