Increasing output current for charge pump circuit

Not open for further replies.

Hi, everyone.
Since the charge pump in the market has limited output current, around 100mA, this will be the problem to power the power hungry devices like amplifiers.
I had modified the circuit and it seems can work. I'll use 2 D type dry cells to power the circuit. Please give me some suggestions because I don't know whether this circuit can work or not.:confused:

1.5V dry cells quickly drop to 1.2V each so the charge pump will have a 2.4V supply.

The transistors have a voltage loss of 1.4V and the diodes have a voltage loss of 1.4V so the output voltage will be less than the input voltage. You made a heater.
