Abstract
A regulated power supply interface has a current feedback and voltage level shift circuit that monitors power supply output (load) current and controllably diverts current to a current reference node. A differential amplifier-based, voltage feedback and voltage level shift circuit monitors the load voltage and controllably diverts output current to the current reference node. A current mode setpoint circuit has multiple voltage dropping current paths, through one or more of which a summation of the diverted load currents are programmably directed, to generate a control voltage for controlling the operation of a pulse width modulator unit of the regulated power supply.
