DC2236A-B

Hey All,

I am working on de DC2236A-B and i adjust it so its output voltage turn to be 22V. As a results was the chip LTC3890 three time broken. I replaced it but i am not sure any more if this board will give the needed voltage. The only thing I have replaced was the resistor divider. I would want to know if i did something wrong. Thanks !!
