Abstract
A programmable AC/DC or DC/DC power supply adapted to compensate for voltage drop in a cable extending to a portable electronic device. The invention reduces the number and size of cable wires and tip components needed to remotely control an output voltage level and an output current limit. The voltage and current programming components are outside the compensation feedback loop.
