Last week I played a lot with SN6505 from TI… So much power in so small SOT23-6. First and foremost, power source for VFD display (30VDC anode voltage, and ~2.5VAC for cathode)… Efficiency at max current 95%! Amazing. Let’s try to get more power!

PCB ordered
I decided to order multiple PCB, to save some shipping cost, and also to test some my ideas too… One of them – DC-DC push-pull converter on SN6505 to power up my VFD. I ordered some Epcos N87 rings, done some calculations in Lite-CalcIT, also researched some available info, and even found a nice book …
Playing with Fusion 360 (instead of designing electronics)
I have a problem. I already prepared things for Phono Preamp (filled shopping card on Digikey and uploaded gerbers to JLCPCB). But to save on delivery, I wanted to order more PCBs at once… So, I brought to life my old projects. Home audio system Badaboom. I already bought some nice neat VFD displays from …
