Abstract

The invention discloses a fast charging conversion device which comprises an input end and an output end, and a main control MCU is arranged between the input end and the output end. A QC protocol auxiliary circuit is arranged between the main control MCU and the input end, and a PD protocol chip is arranged between the main control MCU and the output end; a switch MOS is arranged on the upper side of the main control MCU, and a power supply LDO is arranged on the lower side of the main control MCU; and a first light-emitting LED, a second light-emitting LED and a third light-emitting LED aresequentially arranged on the side, close to the output end, of the right side of the power supply LDO from top to bottom. The stock charger is creatively utilized and transformed into the advanced USBType-C PD charger, so that the fast charging conversion device has the characteristic of low overall cost, and waste of money and resources is avoided.

Description

technical field [0001] The invention belongs to the technical field of charge conversion, and in particular relates to a fast charge conversion device. Background technique [0002] At present, there are more and more devices using the USB Type-CPD protocol as fast charging, such as Apple's IPHONE, mobile phones from Huawei, Xiaomi and other companies, as well as notebooks from Lenovo and DELL. The traditional QC protocol charger still has a large stock market, and the price is cheap. And the new TYPE CPD chargers are often expensive. Take Apple's standard 18WPD charger as an example, the price is 200 yuan, while the price of an ordinary QC charger is around 20 yuan. [0003] In order to cope with this cost difference and actual demand, this device can convert the existing QC protocol charger into a PD protocol charger for use. Contents of the invention [0004] The object of the present invention is to provide a fast charging conversion device in order to overcome the ...
