Yingjixin IP2756 chip has passed the dual certification of PD3.1 fast charging protocol and UFCS integrated fast charging

News from this site on August 23, Yingjixin Technology’s public account announced that its new IP2756 chip has passed dual certification of the PD3.1 protocol and UFCS integrated fast charging protocol.

According to the official introduction, the IP2756 chip is the fifth generation interface protocol IC launched by Yingjixin, which increases the voltage regulation to 10mV/ step, the current regulation is increased to 12.5mA/step.

This chip can be used in products such as chargers, power banks, and car chargers. It is used for fast charging protocol control ICs of USB interfaces and supports multiple fast charging protocols.

This site attaches an introduction to PD3.1 protocol and UFCS integrated fast charging protocol:

USB PD3.1 specification adds an extended power range, the maximum power is extended from 100W to 240W, and 28V is added , 36V and 48V three fixed voltage levels and three adjustable voltage levels.

The maximum current level remains unchanged at the maximum 5A; 100-140W power is 28V AVS, and the voltage range is 15V-28V; greater than 140W to 180W, the power is 36V AVS, and the voltage range is 15V-36V; greater than 180W to 240W is 48V AVS, the voltage range is 15V-48V.

UFCS (Universal Fast Charging Specification) is a new generation of integrated fast charging protocol led by the Academy of Information and Communications Technology, Huawei, vivo, Xiaomi, and OPPO, in conjunction with the joint efforts of multiple terminal, chip companies, and industry partners. It aims to solve the current problems of complex and incompatible fast charging standards on the market; it can also improve the user experience and play a positive role in promoting energy conservation and environmental protection.
