Part Number: LM25184-Q1 Other Parts Discussed in Thread: LM25184 , PSPICE-FOR-TI
Tool/software:
I tried to make some simulation in Ltspice with the unencrypted version of LM25184-Q1(i got this model from TI ). As example i used the illustration of the…
Hi Daria,
I am afraid somebody miscounted the number of turns, and your transformer seems having 27T on the secondary instead of 26T. Please double check.
Thanks,

Hi Ivy,
See below my schematic review:
1. Rfb: I recommend decreasing this value to ~123kohm as recommended by the calculator. Rfb sets the output voltage from a voltage divider from internal VREF from the switching node, so it is very important to set…
Part Number: LM25184-Q1 Other Parts Discussed in Thread: LM25184 Tool/software: 下面是电路的原理图和计算器的理论值，在空载条件下，+18V 电压将被拉低，导致输出关断。我将220uF 电解电容器与 18V 输出电压并联，电压稳定下来。当我连接负载时，输出电压再次不稳定。我测量了 FB 电阻器上的电压，没有严重的干扰。
Part Number: LM25184 Tool/software: Hi team,
I received a question from customer.
Nps is turn ratio so theoretically it's a fixed value, but it should be vary due to the material variation and degree of coupling. And the output voltage accuracy may…
Part Number: LM25184 Other Parts Discussed in Thread: , PSPICE-FOR-TI Tool/software: Hello,
I have tried to upload the library of LM25184 downloaded from TI but I saw is messing the file .libsig, I added to the library the files LM25184-Q1_TRANS.DSN…
Part Number: LM25184-Q1 Tool/software: Customer would like to check sink current at FB pin if EN/UVLO=0V, since they did want to achieve extremely low power consumption during shut down mode.

Dear TI
I consider below condition of flyback of LM25184.
Vin 10~14(12V norminal)
Vout Dual 28V/0.3A 6V/0.4A (equ Single 28V/0.43A)
Transformer result in excel(right image)
Transformer result in web bench(left image…
Part Number: LM25184 Other Parts Discussed in Thread: LM5155 , LM5156 Tool/software: Hi Team,
1. looking at the application circuit of PSR Flyback DC-DC controller - LM25184. the control logic is based at the primary side of the transformer. Can the…
