Part Number:TPS65100
Hi,
Could you tell me the correct way to set the VCOM voltage on the TPS65100?
The datasheet and evaluation kit and set the output voltage at half of Vo1 with equal value feedback resistors, but I can't see where the equation is for the to program the actual voltage when a different value is required.
Please see image of the circuit:below:
My guess is VCOM = Vo1 * (R4/ (R1 + R4)), but it could be VCOM = Vo1 * (R1/ (R1 + R4)),
I need to know the correct way because I am using a chain of resistors to set R4 to cut down on component types, but only one resistor for R1.
Your help would be greatly appreciated. Thanks, John.
