Part Number: LM5181
Hi! I have a power supply on LM5181.
Lpri=32uH Pri:Sec=4:1
Vin=10-17V Vout=5V
I make the power supply on IC LM5181. In general, the source works well. Problems appear at negative temperatures when loaded 0. With a load of 0 mA, large…
Part Number: LM5181 Dear Team
Good day!
Our customer wondering whether he can connect negative voltage to the LM5181 , so he can end up with a negative ground in the output.
like the file below
Please help us to confirm it , Thanks

Part Number: LM5181 Hi team.
Could you kindly give the reference design for LM5181 for the below specifications:
Input: 18-40V (typ=24V)
Output:
1) 32V, 0.05A;
2) 24V, 0.05A;
3) 5V, 0.05A.
Most interested in turns ratio.
According to table 3 of the LM5181…
Part Number: LM5181 Hi,
We are having some EMI issues with our board and I would like to rule out any placement and layout issues with LM5181. The layout is very similar to what is recommended in the datasheet.
Following is the schematic, placement and…
Part Number: LM5181 Hi:
I am using LM5181 to design a 12V isolate power.The schematic diagram is as follows.I have a problem now, the output voltage is correct. but the output current cannot drive the load. The transformer Np:Ns is 4:1.R5 is 121K.Please…
Part Number: LM5181 Hi,
My customer is considering using LM5181.
Why is RRSET around 12.1kΩ?
They would like to know an influence by dispersion of RRSET.

Part Number: LM5181 Hi,
RRSET is designated 12.1kΩ.
However, There is no 12.1kΩ in E24 series.
Can this value alternate others?
Best regards,
