Hi Hernandez,
Thanks for your input, I will go through it.
In mean time I had selected few controller ( LM5180 , LM25183 ) for my requirement and tried recommended calculator tool and performed few simulation as well. The output looks proper and also tallies…
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

Hello
Please provide 'scope images of the SW node.
Also, I have attached the spreadsheet with a 5Vout design.
Please check your component values against the spreadsheet, you
may need to adjust some other values.
Thanks

Hello
I don't think that the LM5180 can do it. But the LM25184 should be able to do it.
I have attached the quick start tool with presumed customer values.
You can use that to experiment with.
Thanks

Hello
The answers to most of your questions can be found in the data sheet and calculator tool for this device.
I have attached the calculator tool with presumed values of customer components.
The current limit can be tested by overloading the output…
Hi
The LM25184 operates under variable-frequency, and it goes through three possible modes of operation as stated in Figure 7-2 in datasheet . The frequency range is 12kHz to 350kHz.
I would recommend using the calculation tool (please see attachment,…

Here are my design parameters, as requested. My final application is an isolated MBUS energy meter reader: https://m-bus.com/documentation-wired/04-physical-layer
The supply requires 36V at 50…
Part Number: LM5180 Our output setting is 11V. But, the output is 11.5V in the actual confirmation.
Could you please advise the possible causes?
Please refer attached for the regulation data and design.

Hello
Your application is the same as shown in figure 8.1 of the data sheet. The BOM is shown in figure 8.2.
Any of the transformers listed in those table will work. They have all been tested.
Also, the EVM for the LM25184 is configured for your application…
