Abstract: An isolated switching power converter is provided wherein a secondary side is valley mode switched to transmit data to a primary side. This provides secondary side regulation without the need for an optocoupler. Data communication between the primary and secondary sides of switching power converters is presented.

Abstract: A power converter with fast discharging to adapt to a load disconnect. The power converter comprises a magnetic component coupled between an input of the power converter and an output of the power converter. The magnetic component includes a primary winding and a secondary winding. A switch controls transfer of energy from the primary winding to the secondary winding according to on and off times of the switch. A discharge circuit is coupled to the output of the power converter. The discharge circuit is adapted to receive a signal indicative of whether the load is disconnected and to decrease an output voltage at the output of the power converter based on the signal indicative of whether the load is disconnected.
