    Some of them will shut down at 1.270V and some at 1.31V max...
    Also there is NO WAY to avoid this OVP due to the design of this chip....

    TIP: A way to avoid OVP on this VGA is ONLY if you play with it's VIDs...
    NO OTHER WAY....

    PLUS that afterwards you NEED to "seperate" the IMAX pin of the chip from the switching frequenccy pin of it because IF you JUST solder a trimmer to ground, when you trim it you may change the IMAX limit of it BUT you - at the SAME TIME - change the frequency of the switching power circuit...
    So you HAVE to seperate those two and have one trimmer for the swiching frequency and one trimmer for the IMAX......
    PLUS that you want another one for the VTT of the core....
