I have a design using a Torex semiconductor DC/DC converter IC: https://www.torexsemi.com/file/x...
That just will not work properly. In fact I have the same circuit in another board design that DOES work using the same exact components, the only difference being the component layout due to size constraints. The circuit that works has the parts located closer to the IC than the non working one, which the datasheet does say that the components need to be as close as possible. The difference in distances between both boards is not that much, but it is what it is.
The symptom on the non-working unit is that any small surge causes the device to shut down, and it will not supply more than 150 milliamperes without shutting down. I get the full 1 amp output on the working design.
I have been fighting with this for over a week now and I need to come up with a backup plan. I was wondering if anyone could recommend a miniature dc-dc module that could take in 12vdc and output 5vdc at almost an amp of current...and be as low profile as possible...5mm max?
