Part Number: LM25184 Other Parts Discussed in Thread: TCAN1043-Q1 , Tool/software: i tried to make a ground shift test for my power electronic (controller module and power module). I found an old post in the TI chat with the title " TCAN1043-Q1: CAN…
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…
Part Number: LM25184-Q1 Tool/software: Hi team,
If minimum peak primary current (36Vin, minimum on pulse=140ns) is higher than 0.82A and the load current decrease, does the device eventually fall into FFM mode?
Or does it keep switching frequency at…
Part Number: LM25184-Q1 Tool/software: Hi team,
The data sheet states that the output voltage accuracy is 1.5%, but will any type of transformer be sufficient?
If it depends on the performance of the transformer, please tell me what specific characteristics…
Part Number: LM25184-Q1 Other Parts Discussed in Thread: LM25184 , Tool/software: Hello,
I have a question based on the transformer selection for the LM25184-Q1. We want to create two outputs of about 7V (350mA) and 15V (30mA) from inputs ranging within…
Part Number: LM25184-Q1 Other Parts Discussed in Thread: LM5185-Q1 Tool/software: Hey there,
We are using the Power Stage Designer tool version 5.0 and LM(2)518X PSR Flyback converter quickstart tool Rev C. to set the Lmag of primary. We noticed 2 issues…
Part Number: LM25184-Q1 Other Parts Discussed in Thread: LM5185-Q1 , Tool/software: Hello,
I am using input 8V to 16V. My desired output is 14V/ 16V with 2.5A output current. Can I use this device?
Part Number: LM25184-Q1 Other Parts Discussed in Thread: LM25184 , LM5180EVM-S05 Tool/software: Hello,
We are using LM25184 for stepping up 15V to 20V with isolation btwn input and output. Please find the below schematic. Note: C63 is DNP in design.

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…
