Abstract
The present disclosure includes a system including a power supply unit that provides an output power and a supply status indicating whether the power supply unit is receiving input power. An electronic circuit is coupled to the power supply unit to receive the output power and a standby control circuit controls turning on and off the power supply unit. A power harvesting circuit generates standby power from the supply status and provides the standby power to power the standby control circuit.
