Hi,
I've designed a TINA TI schematic for a DC/DC step-up converter based on the LM3481. Basically, it is the LM3481EVAL board with just a few minor changes.
I just can't get it working properly. Drain-Source/Gate-Source voltages seem to be correct, but all the current curves don't make sense. Also, the basic function (to create constant 12V output) doesn't work. If the input voltage is changed, the output voltage does so as well.
I would appreciate if someone could have a quick look over the project and give me a tip what the problem might be.
Thank you
Best regards,
Steffen Frensch
