Part Number: LM3478EVAL Hello Team,
Can you share with me what is the purpose/function of Rbypass, as shown on this forum page?

Part Number: LM3478EVAL Other Parts Discussed in Thread: LM3478
Hi,
I am designing a power supply circuit based on LM3478. As it is my first switch mode power supply design it would be great to have design files (Altium or OrCAD) of your evaluation…
Part Number: LM3478EVAL Hi Team, May we request for a 3D model/step file for LM3478EVAL on behalf of our customer? Thanks in advance! Kind Regards, Jejomar
Part Number: LM3478EVAL The layout shown in the picture on the EVM page ( http://www.ti.com/tool/lm3478eval ) seems to be different from what is shown in the User’s Guide. Could you verify which is correct? The reason I ask is that I have a customer who…
Other Parts Discussed in Thread: LM3478EVAL Hi,
Is it possible to obtain the layout data for the LM368 evaluation board as a step file (or something similar). In the datasheet the layout is shown as figures and I didn't find any link on the homepage…
Hello
Iin= Vout*Iout/Vin. 12V * 1.5A / 5V = 3.6A if the efficiency is 100%
Assuming 80% efficiency, your average input current will be about 4.5A.
Assuming 30% margin, my recommendation is to increase your power supply's current limit to 6A.
Than…
Hi Kenneth,
Thanks for the update and considering flyback topology.
My strongest suspicion is still about the SIR610DP-T1-RE3 MOSFET which is used. If possible, I would recommend to test a different MOSFET with lower gs-threshold.
You can also request…
I just received the LM3478EVAL step-up board and out of the box with 5V input this is the gate signal, which has the glitch at the FETs threshold voltage, same as mine.

I have prototyped a solution using the LM3478EVAL board.
The device produces audible noise in the 5-20kHz range due to OVP under light loads.
I am skeptical that reducing L and…
