LM3478: original design

Hi Piet,

Thank you for your interest in LM3478. Sorry but I don't fully understand your question. What do you need in particular?

Thanks,

Yinsong

Dear Yinsong,

As you can see in the attachment I used WBDesign to develop a Boost-Up convertor. I made some change to the design, but the old design is gone. How to get the old design back. I want to make some changes to that design starting at the attached design.

Best Regards,

Piet 

Hi Piet,

I see. Sorry but I don't think Webench can auto-store it if you have not saved the link. Anyway, if you have all the operating conditions, it shouldn't be too hard to re-create it.

Thanks,

Yinsong

Dear Yinsong,

I re-create it (named WBDesign 78) with all the changes I made before. Can you run all the necessary tests to see if everything is OK.

Another question is is there an replacement for D1 (SB20150TR). I choose the TSP20U60S_S1G, but this part is very hard to get. There is an restriction in the height with max of 3.0 mm.

Best Regards,

Piet

Hi Piet,

I'm not sure I understand your question. What tests do you ask for? Do you already have the hardware?

We don't recommend any specific component over others but you can search for any diode that has close specs created in Webench.

Thanks,

Yinsong

Dear Yinsong,

Yes, I have the hardware ready. The test or graphs should be combined to see what the effect is with the changed components. Have the new selected components a better or worse result..
