Since you are driving this with another DC-DC, you are may be violating them. You have way too many unnecessary diodes in there.
I am wondering why The 12V datsaheet actually 12V? DC to DC converters. I’m in the process of migrating to Altium, but the project timescales didn’t fit in with the associate learning the curve – will rectify all the problems for the next project The figures are same while the feedback resistance are different.
Have you cut a PCB or are you doing this on a breadboard? If you have any tips then let me know.

I have attached a datasheeet that shows the general idea of the schematic, as well as a detailed schematic with every component. Power Electronics Search In. Sign in Already have an account?

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.

Ideally, the correct part number should be dataseet up on the schematic. Apr 1, 2. Sign In Sign Up. Share this post Link to post Share on other sites. How good is your 12V? Hence I was unable to find the datasheet. My only other thought is that I’m over-loading the output of the Muratas which are only rated to 1W. The manufacturer’s test is not a netlist test. The schematic lacks enough information to comment specifically. They are definitely NMASC, but that wasn’t a dumb thing to say it wouldn’t be the first time I’d done something like that!
Here are some details of LD: I tried to turn the R1 into 10K. Thanks again for your invaluable comments. The modules seem appropriate for your application. I used to use LD to produce datadheet of 3.
Looking through the DC-DC datasheet, here are the observations: Similar Threads opto isolated h bridge PCB design. Is R26 and its siblings placed next to the driver where datasehet would reduce ringing or is it placed next to the IGBT where it would promote it? Anything less than netlist based electrical testing of the PCB and you are gambling. You’ll need to choose a username for the site, which only take a couple of moments here.
While the schematic looks reasonable, your vatasheet problem may be in the layout. Test application circuit in the datasheet However, I met some problems when I want to produce 5V voltage according to the circuit above. Register a new account. That would be the first place I would look. H-bridge over 6v dc engine. Cascading dc to dc converter with H bridge.
The quality of the layout is a different matter, hence the stray inductance may be an issue – not sure what to suggest other than to remove some of the protection diodes.

What is the point of D7, D8, D9, D10? Posted April 24, Good point about the I’m beginning to run out of ideas – can anyone suggest something to try? Sorry for my poor English,but can anyone give me some suggestions?
