Abstract

Embodiments of the present invention provide a power converter, a control method thereof, and a USB PD charger. The power converter includes a primary side and a secondary side connected by a transformer winding, the primary side includes a primary side controller, the secondary side includes a secondary side controller and a load switch, the primary side is connected to a power source, and the secondary side is connected through the load switch Connected to the load, the secondary side controller is used to control the load switch to control whether power is supplied to the load, the primary side controller has a feedback pin, and the secondary side controller is coupled to the feedback pin of the primary side controller through a feedback element. pin, the secondary side controller has a control pin which is connected to the input of the feedback element. When the secondary-side controller monitors the occurrence of an abnormality, the control pin of the secondary-side controller sends a control signal, and sends it to the feedback pin of the primary-side controller through the feedback element to control the primary-side controller to stop working, so as to be able to Provides additional protection for the primary side controller.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of power conversion, and in particular, to a power converter, a control method thereof, and a USB PD charger. Background technique [0002] Today, USB (Universal Serial Bus) is the main power provider for electronic devices. Many devices today are charged or powered via USB ports in laptops, workstations, docking stations, monitors, cars, airplanes, and even wall sockets. USB has become a ubiquitous power outlet for many small devices such as cell phones, tablets, portable speakers, and other handheld devices. [0003] International regulations require better energy management to meet safety and efficiency requirements. The USB PD (Universal Serial Bus Power Delivery) specification is widely adopted as a power delivery protocol, especially for fast charging designs, by providing more flexible power delivery as well as data on a single cable Maximum functionality of USB. [0004] The...
