Could you please share me what are the possible reasons for the DC DC Converter failures. Application of the subjected DC DC Converter is to separate the power & control ground. We are using DC DC Converter in regulator O/P, even though converter is

We are facing 50% yield soldering Linerar (uModule) DC/DC LGA. The failure is characterized as "flactuation of output voltage." Can some one had the same failure?

Yes we do place "big and heavy" SMT DC/DC:s on most of our board's. Please tell us what brand it is or at least what the package look like?!? For instance we place a different numbers of "heavy" DC/DC converters (40x20mm & 45x25mm) that has the pick-

1. Palm down the GSM and open the safety cover to check input voltage +12VDC (at KDC2 3PL pins 2 to 3) and output voltage +5VDC (at KDC2 2PL pin 4 to 3) at the DC/DC converter. The DC/DC converter is located inside the control panel assembly ("Nose c

How did you convert the touch screen to the monitor and mouse combination? We had the same problem two years ago and tried to do the conversion, but ended up with a new DC/DC power supply card.

The screen we had is a Planar EL7768MS. There is a small DC/DC power supply board attahced to the back of the touch screen. That PS board was toasted and caused the failure of the screen. Steve

Thanks for the detailed information. I have a spare dc/dc converter on order to try swapping them. Another note is all dc power is cut out by the pdp.ps1, not just 12vdc. 24vac power remains.

Just one more thought - we had an issue with +12V supply for VME rack. One tantalum cap in the DC/DC converter module for linear encoder interpolator shorted it out, but oddly enough - not always. We ended up hooking scope to all PSU voltages and whe
