Hello everyone,
I have an issue with the MAX868 regulating charge pump. I am currently using a 5V power supply and wish to convert that to a -10V power supply. I have attached the following schematic that shows how I am currently connecting it. Pin2 is just the output of the chip that should be at -10V but when I connect it together I get around -5V at most instead (using a voltmeter). My question is what am I doing wrong in which I am getting a lower value as an output.
Let me know if you need more information.
Thanks.
