For all I know the problem is that you are using a 5V zener, but I have no way of knowing because all I see is “zener” p.

Apr 1, 3. Discussion in ‘General Electronics Discussion’ started by datasheet, Apr 1, Ask a Question Want to reply to this thread or ask your own question? Have you stressed it and thoroughly tested it? Good point about the While the schematic looks reasonable, your real problem may be in the layout.

You’ll need to choose a username for the site, which only take a couple of moments here. Going on a slight tangent But I can not imagine that violating them would cause the device to fail.

VO has a minimum operating voltage of R26 is about 2.

If you have any tips then let me know. DC to DC converters.

Looking through the DC-DC datasheet, here are the observations: Posted April 24, I am wondering why Still no luck on the DC-DC. H-bridge over 6v dc engine. Was it a “golden board” test or a real netlist based test? I tried to turn the Xatasheet into 10K. They are definitely NMASC, but that wasn’t a dumb thing to say it wouldn’t be the first time I’d done something datashfet that! There are precautions about input voltage rise time at the bottom of Selection Guide on first page.

Sign In Sign Up. The Murata DCs do have a minimum current requiment, although the data sheet is a bit convoluted and I was confused as to what it was.

I have gotten REALLY busy due to some issues coming l593 out of nowhere at work and have not had a chance to post here or eat or sleep or Already have an account?


Apr 1, 2. ON Semi 20V Zener. How do you know that the circuit is exactly what you have drawn here? How good is the layout?

Apr 6, 8. Unfortunately, that is beyond the scope of what I can help you over the internet. My philosophy has always been to go overboard with the protection in the PCB design then decide later whether I want to populate those parts.

You have way too many unnecessary diodes in there. I have no reason to suspect the IGBTs which seem rock-solid so far.
