ADP1048 GUI SUPPORT 2

Hi Guys,

 

My ADP1048 prototype design is reading the input and output voltages incorrectly. Because my feedback circuit includes a differential amplifier followed by another resistor divider, it is possible I am entering the values into the board settings file incorrectly. I have attached a jpg of the divider network in my design for reference. Because of the resistor divider at the output of the amplifier I used a lower resistor value in the GUI of 5kohm instead of 10kohm. Using these values the ADP1048's reading is out by a factor of 2 i.e. 200V at the output is read as 100V by the ADP1048.

 

Can anyone advise on what values I should be entering into the board settings file within the GUI?

 

Thanks,

 

Edward
