I am wondering why After that, you can post your question and our members will help you out. If you have any tips then let me know. How good is the layout? There are precautions about input voltage rise time at the bottom of Selection Guide on first page.

Could it be over-shooting beyond the DC-DC’s maximum voltage? But if the DC-DC fails to start up, what happens to the downstream circuits? Here are my thoughts: They are definitely NMASC, but that wasn’t a dumb thing to say fatasheet wouldn’t be the datashest time I’d done something like that!

All the parts start with MPD and start with 5W.

H bridge loading problems. Thanks again for your invaluable comments. H-bridge over 6v dc engine. Sign In Sign Up. A few general comments: I have attached a pictures that shows the general idea of the schematic, as well as a detailed schematic with every component. Sorry for my poor English,but can anyone give me some suggestions? Discussion in ‘General Electronics Discussion’ started by stube40, Apr 1, How do you know that the PCB is manufactured correctly?

Apr 1, 2. You’ll need to choose a username for the site, which only take a couple of moments here.

While the schematic looks reasonable, your real problem may be in the layout. Hence I was unable to find the datasheet. ,5973 are some details of LD: Since you are driving this with another DC-DC, you are may be violating them.

The schematic lacks enough information to comment specifically. You need to be a member in order to leave a comment.

Apr 6, 8. Unfortunately, that is beyond the scope of what I can help you over the internet. Testing out of circuit against a reference device shows they truly are dead.

How do you know that the circuit is exactly what you have drawn here? The figures are same while the feedback resistance are different. Have you considered the possibility that you were delivered wrong DC-DC converters and you are installing 5V input voltage devices into 12V? 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.

ON Semi 20V Zener. In the same circuit, the voltage is 3. How do you know that your layout is correct? Ideally, the correct part number should be showing up on the schematic.

Apr 1, 1. 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.

Good point about the Posted April 24, Test application circuit in the datasheet However, I datqsheet some problems when I want to produce 5V voltage according to the circuit above.

Have you stressed it and thoroughly tested it? The input is 24V DC. 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.

The manufacturer’s test is not a netlist test.
