Problems solved by technology

However, traditional dual USB-C interface PD chargers usually use a dual-channel transformer solution. Each transformer independently controls one USB PD power output, and its power control is not flexible enough. Therefore, how to improve the dual USB-C interface PD charger The problem of flexibility needs to be solved urgently

Abstract

The invention provides a power adapter and a charging control method. The power adapter comprises a rectifying circuit, a first adapter, a second adapter, a first PD protocol chip, a second PD protocol chip, a shunt switch, a first output port and a second output port; the rectifying circuit is connected with the first adapter and the second adapter; the first adapter is connected with the first PD protocol chip; the second adapter is connected with the second PD protocol chip; the first PD protocol chip is connected with the first output port; the second PD protocol chip is connected with the second output port; the first adapter is connected with the second adapter through the shunt switch; the first PD protocol chip is connected with the second PD protocol chip; and the first PD protocol chip and the second PD protocol chip are both connected with the shunt switch. According to the embodiment of the invention, the flexibility of the PD charger with the double USB-C interfaces is improved.

Description

Technical field [0001] The present application relates to the field of electronic technology, and more particularly to a power adapter and a charging control method. Background technique [0002] With the rapid development and popularity of USB Power Delivery, USB PD, the rapid development of fast charge technology, more and more charging equipment support USB PD fast charge technology. Especially in high-power USB PD applications, the application requirements for multi USB interface charging equipment are getting bigger. Among them, the most typical application is a PD charger occasion of a dual USB-C interface. The traditional dual USB-C interface PD charger typically uses a two-way transformer program, each transformer separately controls all the way USB PD power output, and its power control is not flexible, so how to improve the PD charger of Dual USB-C interface The problem of flexibility needs to be resolved. Inventive content [0003] The present application embodiment p...
