I am having the following problem.
I need 10 times a power supply of 9.5V/1.2V for an battery charger.
At first I was thinking of a lab power supply, but if accidentally more than 9.5V is offered, then everything would blow up.
My issue is that I have to deal with a variable charge current per charge circuit that matches the following charge current values that can be selected: 256mA/512mA/768mA/1024mA.
A simple switcher is not a solution, because then I would need too much components per charge circuit.
Does anyone have a solution for this, maybe to make sure that my current will never get higher than 9.5V???
Maybe a lab power supply that you can only adjust by means of a potential meter that cannot too easily be reached or something??
