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 Hi there,
We are verifying LM5180 for our power supply application.
I am referring SNVU592D and using the evaluation board LM5180EVM-S05 as it is. ( only deviation that input capacitor is 220 microfarad - higher than proposed in design…
Part Number: LM5180
Hello Team,
Among the transformers you have evaluated, the one that has been chosen on the LM5180EVM-S05 is relatively too big for the application I'm looking at.
Optimal would be an height lower than 10mm, in the range of 6mm…

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

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…
