The 45W PD charger manufacturer tells you that PD power adapters generally have 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 logic requirements for multi-port control. The 45W PD charger manufacturer tells you that there are also display methods and control methods. There are different needs. As for function customization, it is precisely the traditional strength of MCU, which can support the diverse needs of customers.

A pd charger is a power adapter with PD protocol. The pd protocol is a protocol for fast charging. It requires charging power to meet the standards proposed by the USB standardization organization, which is very common in fast charging technology. The 45W PD charger manufacturer tells you that there are usually two protocols for fast charging, namely the QC protocol and the PD protocol. Since major manufacturers have different requirements for charging efficiency during design, they need a unified specification to limit them, so pd Protocols and QC protocols follow.
The charger (charger) can be divided into power frequency machine and high frequency machine according to the working frequency of the designed circuit. The manufacturer of the 45W PD charger tells you that the industrial frequency machine is designed on the basis of traditional analog circuit principles. The internal power components (such as transformers, inductors, capacitors, etc.) This model has strong resistance to harsh grid environment conditions, and its reliability and stability are stronger than those of high-frequency machines.
