DC to DC converter
Hi everyone,I have a source of 2.5V but i dono how much is the currect, i used a voltage doubler circuit and gain an output voltage of 5V ,but im still unable/ or no idea how to measure the current. When i connect a resistor across the the output voltage(and put the multimer in series) it gives me 0A.

Actually i wan to use this 5 V to create a input voltage for my cellphone charger but when i plug the output of the voltage of the voltage double into the phone the output voltage becomes 1.2V and it is no longer 5V.

Can anyone tell me why is this happening?Is it because the current is too low?and is there anyway of solving this problem?

Re: DC to DC converter. Measure output current
Can you share us the specification, part number of your voltage doubler, schematic etc.?
