Abstract
A phase-redundant voltage regulator can include multiple regulator phases connected in parallel between a common regulator input and a common regulator output. Each regulator phase includes a voltage regulator that receives an input voltage and drives a respective output voltage. The voltage regulator also includes a plurality of linear regulators, each having a linear ORing device electrically connected between the regulator output of a respective regulator and an output of the linear regulator. The voltage regulator also includes an amplifier having inputs electrically connected to a remote voltage sense input and to a reference voltage input. An output of the voltage regulator is electrically connected to an input of the linear ORing device. The amplifier controls the linear ORing device to drive a voltage on the output of the linear regulator equivalent to a voltage on the reference voltage input.
