ABSTRACT:
A power supply includes a voltage regulator for generating a regulated voltage in response to an input voltage and an error signal, first and second output terminals connected to the voltage regulator for coupling the power supply to a load, first and second sense terminals and a sensing circuit for generating the error signal. The sensing circuit includes a high input impedance differential amplifier having first and second inputs respectively coupled to the first and second sense terminals for measuring a sense voltage between the sense terminals. The power supply may be operated in a remote sensing mode or in a local sensing mode. In the local sensing mode, no connections are required between the sense terminals and the output terminals.
