SSTC-Driver PCB 1.2
« on: October 30, 2018, 08:16:30 AM »
Hi guys!

I have been working on a PCB template for the standard cd4046 sstc driver you find all over the internet (original by scopeboy.com/Steve Conner). I didn't design any of this, I just added a second pair for each UCC, inorder to drive these bigger GDT's too, without breaking a sweat. You can just use two instead of four UCC's but I went more indept in my documentation. If you want to know something, just let me know.

Now here's the deal. I am willing to share the gerberfile and the component list with you, to use for your project's. But there are a few points I want to clarify:
  • I don't want anyone making money on this.
  • It is not finished and I still update the files.
  • I haven't tested this design yet.

For anyone interested: I am also working on an interrupter board with staccato interrupting. I will probably upload them later on too. If anyone sees any design flaws please let me know.

Hi Fumeaux and welcome to HVF :)

Thank you for sharing the design and files.

I can not open the files from my current location to check the routing, so I just wanted to ask if you have all unused inputs tied as specified in the datasheet "Unused inputs must be connected to VDD, VSS, or another input". This is often a root cause for instability when inputs are left floating and they can cross talk internally in the IC.

Just for reference to everyone else, the original source and comments from Steve Conner: http://www.scopeboy.com/tesla/dwsstc/wk2.html

Hi Mads!

Thank you for your tip. I made sure that i only have the pins not connected, that others didn't connect too, so it should be fine (those are just outputs, no input is floating).

It's great to be here, cheers.
