  • Forum Post: UCD9240 temperature issues on start-up

    EDGAR BROWN
    We have a design with an UCD9240 and three single-phase power rails. We have found that after the system warms-up (UCD9240 case temperature with a thermocouple attached ~65°C) we get semi-random rail failures. Some rails will come up, but at least one of the rails will fail to start. This shows...

    After more testing and some board modifications we realized that the problem was not the UCD9240 but the PTD08A006W modules, the faults seemed to be _somewhat_ legitimate. Under hot conditions the module voltage might be transiently dipping below the minimum of 4.75V causing an apparent drive transistor...

    EDGAR BROWN
    We have a design with an UCD9240 and three single-phase power rails using the PTD08A006W. We are having some trouble debugging start-up problems as the system seems to log faults on all the rails during shut-down (it could be start-up, but this seems less likely). After what seems like a normal shut...

  • Forum Post: Re: 5V operation of PTD08A006W

    EDGAR BROWN
    Mark, We finally figured the problem out. It was not Noise after all (at least not in a simple way), but it was not inrush current either (again not in a simple way). After much probing we realized that several of the systems had a ~60kHz ~20mV to ~40mV oscillation on the 3.3V power (small enough...

    EDGAR BROWN
    We have several similar designs using a UCD9240 in a system driving either three or four PTD08A006W to provide multiple (single phase) rails. These rails are relatively low-current (considerably below rating), and we only use the PTDs for design expediency. After some issues (many of which can be found...
