Part Number: LM5180DESIGN-CALC Other Parts Discussed in Thread: LM5180 , LM5180-Q1 Dear Technical Support Team,
Hello,
I am a hardware design engineer currently working on a high-voltage automotive system (COD Heater). I am setting up circuit simulations…
Part Number: LM5180DESIGN-CALC Tool/software: Hi,
I've downloaded LM5180DESIGN-CALC sheet and says to me that the file is protected from edition. In this mode, I couldn't change parameters.
If I give edition permits, the graphics disappear and i get…

Part Number: LM5180DESIGN-CALC Other Parts Discussed in Thread: LM5180 We are design a high output voltage/input voltage ration flyback. We really like your spreadsheet, but why the transformer ration does not allow to go higher than 1:4 in your spre…
Part Number: LM5180DESIGN-CALC Tool/software: WEBENCH® Design Tools Is it possible to process transformers with a turns ratio of 1 : n (n > 1) with the tool? For example, if I enter a turns ratio 1:2 I get the error message #VALUE!
In the second file titled "example_lm5180.." there needs to be a Diode from SW to VIN to loop back that transformer current.
The Zener may not always be necessary but the DF diode is.
Also the EN resistor arrangement is incorrect. Did WEBENCH give…
Part Number: LM5180DESIGN-CALC Other Parts Discussed in Thread: LM5180 Hello,
my customer is currently designing the power supply for their isolated gate driver and they are currently evaluating the LM5180 with their transformer. However parts or macros…
Hello Mauro,
All these parts have similar regulation methods, VOUT is varied based on the RFB values chosen and also transformer turns ratio. You can use design calculator for your design: LM5180DESIGN-CALC Calculation tool | TI.com
