Part Number: LM25180 Other Parts Discussed in Thread: LM5180 , LM5185 , LM25185 Tool/software: Hi,
I want to use WEBENCH to simulate LM25180 design.
Unfortunately I can't change the output voltage (default 5V);
When I set current to 0 I get
When…
Hi David,
Thanks for your response.
Yes, I have contacted the coilcraft team. Today i got reply saying that they are working on my request. Also, they proposed below one reference part supported for LM5185 design,
ZD2250-AE, ZE2432-AE Flyback Transformers…
Hi Hayashi-san,
Thank you for reaching out. This is about 100W and I believe it is beyond the LM5180's power capability because it has internal fixed current limit at 1.5A.
In stead, you may consider the LM5185, which is a controller employing external…
Hi Ravi,
Thank you for reaching out. Your total load is about ~90W, and the LM25184-Q1 cannot support it due to its internally fixed current limit at 4.1A typical.
Instead, I would recommend the LM5185-Q1 PSR flyback controller, which employs an external…
Part Number: LM5185EVM-SIO Other Parts Discussed in Thread: LM5185 , Good evening at all;
I would like to create a simple PSR Flyback DC/DC Controller for example with the LM5185 features approximately: Vin 30 to 65 Volts and Vout of 30 Volts 3A. Without…

Hi John,
Did you ever used our design calculator to help you design, which can be downloaded at the following link?

I just ran your numbers in, and the calculator showed it would not deliver 24Vout @1…
Hello Marshall,
Thank you very much for your reply.
I think LM25185 is a controller for Fly-back and the device could be used for the power supply. Do you think it is difficult to design the power supply using LM25185?
Could I ask you one more question…
