Abstract: A first terminal receives a first DC voltage. A switch selectively couples the first terminal to a second terminal providing an output. A control circuit selectively actuates the switch in response to a comparison of the first DC voltage to a second DC voltage. A low-dropout (LDO) linear voltage regulator, connected between the first and third terminals, operates to provide the second DC voltage from the first DC voltage.

Abstract: An apparatus is for testing a device to be supplied with power via USB Power Delivery (USB-PD). The apparatus includes at least one USB Type-C connector configured to be connected to the device to be supplied with power to be tested, the at least one USB Type-C connector including a power supply terminal. Processing circuitry of the apparatus is configured to verify that a voltage at the power supply terminal is lower than a first threshold, verify a role of the device, generate requests representative of power supply configurations supported by the role of the device, and verify compatibility of the power supply configurations supported by the device with standardized power supply configurations.

Abstract: A voltage source device includes a voltage converter configured to generate a supply voltage at an output node of the voltage converter. A current source is configured to apply a current to a first output terminal of the voltage source device in order to detect a cable voltage drop. A compensation circuit is configured to generate a feedback signal based on a voltage at the first output terminal. The supply voltage is generated based on the feedback signal.

Abstract: A method can be used for managing a power supply voltage on an output power supply pin of a USB Type-C source device coupled to a USB Type-C receiver device via a USB Type-C cable. A first measurement of a first voltage on a channel configuration pin of the cable is performed when the receiver device is not powered and a second measurement of a second voltage on the channel configuration pin is performed when the receiver device is powered. A difference between the first and second voltages is calculated and the power supply voltage is modified as a function of a value of the difference.
