First of all can a device that is constant current also be at the same time constant voltage? In my head I just could not grasp how this device can work.
Individually I understand how it works, constant current supplies adjust the voltage to sustain the target current, constant voltage supplies work by having some feedback loop circuit that tries to maintain the voltage most power supplies are these.
Now devices such as these XL4016 are said to be constant current constant voltage. They even have 2 potentiometers to adjust constant current and voltage. For constant current to happen, the voltage must be varied, but we cannot have that as we also need to have a constant voltage.
Assuming that it works, and I set it to 10V and 1A. what will happen if I place a 1k resistor on the output? Will 10V @ 1A will be forced into that resistor? No matter the resistance I placed 10W will always be on that load, which doesn't sound right.
How is this achieved, or am I being misled here?
