What's the difference between pd charging line and ordinary charging line?
This article will explain in detail what is the difference between pd charger and ordinary charger. I think it is very practical, so I share it with you for reference. I hope you can get something after reading this article.
Difference: the charging speed of pd charging line is faster, while the charging speed of ordinary charging line is slower. Pd charging line will automatically stop charging after charging, making the whole charging process safe and efficient; ordinary charging line will automatically change to trickle-down charging state after charging.
The difference between pd charging line and ordinary charging line
1. Charging speed:
Pd charging line integrates quasi-resonant current mode controller and power MOSFET, which has the characteristics of high performance, low standby power consumption, low cost and so on. Because the charging specification of ordinary charging line is generally 5V2A, and uses constant current and constant voltage charging mode, the charging speed is slow.
2. the current conversion is completed after the charging is completed.
The chip on the pd charging line can control the charging process, and automatically stop charging once it is full, making the whole charging process safe and efficient. And the ordinary 5V2A charging specification line, generally after the battery is fully charged automatically changed to trickle-down charging state.
For the pd charging line, the ultra-low standby power consumption and the best efficiency in the full voltage range are achieved through the three-mode hybrid modulation technology of QR-PWM, QR-PFM and Burst-mode and the low power structure technology of special devices. At the same time, it provides comprehensive and excellent intelligent protection functions, including output overvoltage protection, periodic overcurrent protection, overload protection and soft start function.
For ordinary charging lines, there are few peripheral components, which is relatively simple, and the intelligent power MOSFET with 650V high avalanche capability is integrated internally. The circuit design is simple, easy to implement, and the price is low.
