Part Number: LM5180 Tool/software: Hi. using LM5180 dual out put
Transformer design Nps = 1.2 , Lm = 40uH
Output Voltage = 20V , 0.1A
When Rfb = 300K and Rset = 16K, the output voltage is 20V. Is it possible to change Rset to 12.1K? Will there be any…
Hi Hailong,
First, the LM5180 has fixed current limit which you can not change it, but you can directly refer to the current value. The LM5185 has adjustable current limit which you can change by changing the Rcs resistor value. The Rcs converts the current…
Hi Frank,
1. The Dclamp replaces the usual RCD snubber to cope with the turn-off voltage spike on the internal FET. The voltage rating should be greater than the reflected output voltage, namely Nps x (Vout+VF), then it will not affect Vout.
2. The output…
Hi Titouan,
May I assume the issue is resolved so I can close the thread? You are always welcome to re-open it by adding a new post, or start a new thread.
Good luck in your project.

Part Number: LM5180 Tool/software: Hello, I'm designing a power supply that will be able to provide high voltage (about 500-600V) low current (on the order of 1-2 mA) AC. I have a working solution, but I'm not satisfied with its footprint and absence…
Part Number: LM5180-Q1 Tool/software: When I try to run a PSPICE simulation for this part, I keep getting an error that there are less than 2 connections at the TC node. I have connected a resistor between the TC and RSET nodes, and in the .CIR file…
