Abstract
A system and method reduces power consumption by an electronic power control system when a controller of the electronic power control system reduces sense signal monitoring during a standby mode of the controller. The electronic power control system includes a controller to control a switching power converter. The controller operates in at least two modes, standby and active modes. Energy savings during standby mode can be achieved in a variety of current and/or voltage sensing configurations. During the standby mode, the controller generates a signal to at least intermittently disable sensing of an input voltage to the switching power converter or at least intermittently disabling sensing of an input voltage and an output voltage. Disabling sensing reduces energy losses associated with an input voltage sense signal itself and with circuitry in the controller used to process the input voltage signal.
