Part Number: LM25180 Other Parts Discussed in Thread: LM5180EVM-DUAL , LM5180
Team,
Could you please help with the below question: 1) LM25180 datasheet section 9.2.2 and 9.2.3 show two dual output example with galvanically coupled output voltage. We need…
Part Number: LM5180 Other Parts Discussed in Thread: , LM25180 , LM5161 , LM5017 Hi
We are testing EMI/EMC compliance testing of our product which is based on LM5180 converter IC.
We are facing issues in the Surge Immunity Test (IEC 61000-4-5) as the LM5180…
Hello Vincent,
There are some things to consider here:
1. If they need a simple ready to go module they can use UCC12050 and parallel 4 of the units together. The advantage of using this part is the integrated transformer reduces the total BoM and the…

Have you put a y-cap between GND and S-GND which may helpful for the high frequency EMI, you can try 1nF see whether it helpful.
Hi Daniel,
Yes, I have a Y-cap on the board already. Sorry I forgot to show that on my schematic. It…
Hi,
You might want to try this EVM instead because this one is designed to have 15V output

Also for transformer you can compare with this one

It seems that your transformer leakage inductance…
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…

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…
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…
Hello
The best way to estimate the losses and efficiency for the LM25184 is to use the calculator tool on the website.
I have attached it here for your convenience.
Thanks
