Abstract
A device can be used for managing for managing the supply voltage on an output power supply pin of a USB Type-C source device that includes an AC-to-DC power converter for delivering the supply voltage. The source device is capable of supplying power to a receiver device. A power supply controller includes a first circuit configured to deliver a signal for discharging a capacitive network coupled to the power converter and also includes a second circuit configured to deliver, at the same time as the discharge signal, a new setpoint signal, corresponding to the new voltage delivered, to a control input of the power converter. A delay element is coupled between an output of the second circuit and the control input.
