Part Number: LM5180EVM-S05 Other Parts Discussed in Thread: LM5181 , LM5180 Tool/software: Dear support,
i used calculator to help me with the design (see attachment) and then i did some tests on EVB.
As you will see, i have 5V input voltage and i need…
Hi Akihisa,
1. 15V/2A,3A is too large power for LM25184. In my opinion, customer should consider a flyback controller.
2. You can send the attached calculation tool to your customer. They can learn more insight principles if they are interested.

I've completed the design calculator; maybe you can have a look at it.
I have to mention that our turns ratio of 1.33:1 was not available in the selection, so i selected 1.5:1.

Hello Tim,
Thank your for the quick reply. LM25183, LM25184 PSR flyback quickstart tool revA.xlsx
The peak input current is not given in the quick start file.
Kindly find the attached excel sheet .
Hello
Can you send your schematic.
Also, i have attached the calculator tool for this device.
Can you fill it out and see if your component choices match.
Does the issue occur at a certain load and/or input voltage ??
Or does it appear after a short time…
Hi Paul,
Thank you for designing with the LM4160A. In a fly-buck topology the secondary side is cross regulated, which is derived by the well-regulated primary side voltage via transformer coupling, minus the secondary diode voltage drop and also some…
Part Number: LM25184 Hello TI Team,
We are implementing a DC-DC converter where our input voltage is 34 Volts and we are trying to get dual output of +22V and -6V. We are using the excel sheet given by the TI for LM25184.
Our transformer…
Part Number: LM5180-Q1 Other Parts Discussed in Thread: LM5180 , LM25183 , TINA-TI Hi Team,
I'm currently working on Fly-back topology based Bi-polar supply generation for Mosfet Gate driver supply.
As of now I selected few parts ( LM5180 , LM25183 ) which…
