Discrete Devices, ICs Improve Inverting Charge-Pump Design
04.25.2016 · Circuits
An inverting charge pump takes a positive supply voltage and generates a negative supply from it. Discrete-design charge pumps can offer reduced output impedance, reduced output-ripple voltage, controlled charging currents, and higher working voltages compared to IC-only pumps. The 15-V supply level shown is not handled by presently available ICs, but it has always been an objective to include ICs for cost reasons. This circuit is a step toward that goal...
