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. Apr 1, 4.

The input is 24V DC. Posted April 24, What is the point of D7, D8, D9, D10? Going on a slight tangent Already have an account? Apr 1, 1. How are you preventing cross conduction on the bridge? The 12V line is fairly stable, based on a L which is only loaded with around mA a fraction of what it can handle.

Testing out of circuit against a reference device shows they truly are dead. R26 is about 2. My only other thought is that I’m over-loading the l55973 of the Muratas which are only rated to 1W. Saying all that, it is a fairly simple design and so far my manual inspection has found no reasons to be concerned.
Could it be over-shooting beyond the DC-DC’s maximum voltage? I think early experiments have shown that there is ringing and it may well be causing problems. Did you pay for “electrical test” of the PCB? I have not bothered to check the pin-out of all the parts. How do you know that the DC-DC failure is a primary failure and not a secondary failure? Thanks again for your datashwet comments.
But if the DC-DC fails to start up, what happens to the downstream circuits? 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.
Cascading dc to dc converter with H bridge. Good point about the In the same circuit, the datashet is 3. If not, all bets are off. Have you considered the possibility that you were delivered wrong DC-DC converters datzsheet you are installing 5V input voltage devices into 12V?
