Part Number: LM5180-Q1 Other Parts Discussed in Thread: LM5181 , LM5180 , SN6501
Hi,
I cannot achieve the required output characteristics. Almost all denominations are calculated according to the datasheet. The transformer is selected close in inductance…
Part Number: LM5180-Q1 Other Parts Discussed in Thread: LM25184 , LM5180 Hi,
According to the datasheet, I determined the feedback resistor for the 3.3 output voltage. However, I get more than 30 volts at the output, and there is no reaction to changing…
Part Number: LM5180 Hi Team,
I can find Pin FAME for LM5180-Q1 on E2E thread but Is it OK to use it as LM5180 pin FMEA as well?

Part Number: LM5180-Q1 Hi, Good day. I hope you are well. Our customer is using the PSPICE model for the and they have the following question. "I'm using the LM5180-Q1NGU_TRANS spice model in pspice ti 2020 It is hooked up correctly, but the internal…
Part Number: LM5180-Q1 Hi experts,
I have some questions about LM5180-Q1 Flyback design to check with you. Thank you.
1. Is there any need to add dummy load at the output? If yes, what value is suggested?
2. There are three modes of this device, FFM,…
Part Number: LM5180-Q1 Hello team,
can you confirm if we can regulate the output voltage with the Rset resistor? We tested it with the EVM (modified), it works well. The config makes sure the FB current should not get larger than the recommended 100uA. …
Part Number: LM5180-Q1 Hi teams
Customer want to change the RSET value to output differenet voltage. Any potential risk to do so?
Any recommend range about the RSET value? Thanks.
Hi Ryo,
