PD power adapter is a power adapter with PD protocol. What is PD protocol? The full name of PD is PowerDelivery, which means power transmission management in Chinese. PD charging protocol is a power transmission protocol announced by the USB-IF organization. USB-Power Delivery can The type-c interface is increased to 100W.
USB-Power Delivery is one of the mainstream fast charging protocols, and it is a fast charging specification formulated by the USB-IF organization. USB PD increases power delivery through USB cables and connectors, and expands the cable bus power supply capability in USB applications. This specification enables higher voltages and currents, delivers up to 100 watts of power, and can freely change the direction of power delivery.
The current PD power adapter generally has two interfaces, USB A interface and USB C interface. From the perspective of function definition, the core function of PD power adapter is PD fast charging.
Entering the era of fast charging, the definition of a power adapter will no longer be as single-function as a traditional power adapter. Different customers will have different logical requirements for multi-port control. In addition, there will be different display methods and control methods. For function customization, it is precisely the traditional strength of MCU, which can support the diverse needs of customers.
The new PD charger has obvious advantages for a third-party PD charger. It has a wider charging range and better compatibility, just like an all-round sports player. "SK-PD45-001 PD charger" adopts a single-port output mode, the output power is 45W, supports 5V3A, 9V3A, 12V2.5A, 15V3A, 20V2.25A five charging voltages, and the stability is very strong.
