Hello all,
I have two switch mode regualtor ICs one capable of delivering upto 40Vout and other upto -5V.
The input voltage for both the ICs is same from 4.5V to 40V.
To control the output voltage of this two converters I have a digital potentiometer.
Input voltage range for both SMPS IC
Vin - 4.5V - 40V
Vout - Pos DC-DC converter to 40V (LM25117-Q1)
Vout Neg DC-DC to -5V (LTC3863)
I am not able to get if i need a comparator circuit or an opamp if I need at one output pos voltage and at the other output negative voltage
Both will be controlled with the help of dsPIC30F4011 PIC which has a CAN interface
Thank you
