Abstract

The invention discloses an adapter device based on a PD protocol and a charging method. The device comprises a device entrance, a master control MCU, an LDO power supply module, a VBUS voltage detection unit, and a device exit. The device entrance is connected to a PD adapter power supply, and the device exit is connected to a traditional notebook. The VBUS voltage detection unit is between the device entrance and the device exit and is connected to the device entrance through CC1 and CC2 paths. The LDO power supply module and the VBUS voltage detection unit are connected to the master control MCU and are connected to the VBUS voltage detection unit. According to the adapter device and the charging method, a problem that an existing PD adapter can not be compatible with traditional notebook charging is solved, and the PD adapter power supply outputs specific voltage needed by the traditional notebook to the traditional notebook to carry out charging.

Description

technical field [0001] The invention belongs to the technical field of adapters, and in particular relates to an adapter device and a charging method. The traditional adapter charging method is especially suitable for charging a traditional notebook computer with a PD adapter power supply. Background technique [0002] In our life, there has always been the problem that the notebook power supply is not universal. Some notebook power output is 16.5V, and some notebook power output is 19V. As a result, resources in our work or life cannot be effectively shared. When USB-IF released the USB-TYPEC unified interface and PD protocol, future notebooks will definitely use the TYPE-C interface and PD protocol as standards, and the adapters between computers can be shared with each other. [0003] However, for the hundreds of millions of traditional notebooks currently on the market, the standard voltage points in the PD2.0 protocol are 5V, 12V, and 20V, and the standard voltage poi...
