With the rapid development of smartphones and APP applications, it is obvious that battery life is becoming less and less useful! Limited by the battery technology, it is difficult to make a big breakthrough in the short term. The fast charging technology that has taken a different approach has not only become the standard of mobile phones, but also has been applied to its best companion "mobile power".
However, as the companies currently led by Qualcomm, MTK, Huawei, OPPO, and Samsung have each launched their own fast-charge technology, they are each camp-based and incompatible with each other. Therefore, as a mobile phone accessory product, mobile power must not only keep up with fast charging. The speed of development requires that products must be quickly compatible with many fast-charge agreements on the market, which brings a lot of technical challenges to enterprises.
From April 11th to 14th, at the Global Sources Electronics Show & Hong Kong Spring Electronics Fair held at AsiaWorld-Expo in Hong Kong, Ballyda and Tech Sea Technology released the industry's first two-way 60W type-c PD mobile power supply with built-in 6 20650 specifications of 3350mAh power batteries, performance, battery speed up to 4 times! At the same time support Google, Apple MacBook and other PC fast charge, and compatible with other mainstream fast charge protocol two-way fast charge, high versatility.
Figure: Support type-c two-way fast charge, input and output have achieved 60W, the highest 45W relative to the millet has reached a new level; the average conversion efficiency of rated power reached 94.5%
It is worth mentioning that this 60W bidirectional type-c/PD mobile power solution is provided by the core manufacturer of type-c. It adopts the CSU38M20 independently developed by Xinhai Technology as the master MCU, and the dedicated PD protocol chip CSS34P16 which supports the Type-C PD protocol and is compatible with other fast charging protocols. Under the current fast protocol technology of multi-protocol coexistence, it has the pole. Great competitive advantage.
Figure: The battery adopts 2 series 3 and structure, the total capacity is 20000mAh, and the typical capacity is 72Wh. The single-sided PCB board design effectively reduces the processing cost, enhances the heat dissipation, and is cost-effective.
In fact, the USB PD protocol introduced by the USB-IF organization has greatly optimized the charging experience, including output power up to 100W, bidirectional input and output, simplified USB interface, optimized power management, and support for PC/tablet/PPS. Power transmission of equipment, etc.
From the USB function definition of Ballyda mobile power supply, we can see that each fast charging protocol is gradually unifying to the Type-C PD protocol, while the core technology supports the fast mass production of CSU38M20+CSS34P16 Type-C fast charging mobile power. The solution will greatly accelerate the popularity of the USB Type-C PD protocol in the field of mobile power.
What is expected is that this year's USB-IF organization released the important update of USB PD3.0 based on Type-C interface, which will inject new impetus into the industry. The competition for fast charging standards will begin to enter the unified standard and rapid development path. Enjoy the convenience brought by the PD protocol.
Xinhai Technology will continue to promote the unification of the fast charge protocol, launch special chips supporting PD3.0 and PPS for TYPE-C applications, and establish a more complete ecological solution to help the industry develop!
Figure: Launched PPS (Programmable Power Supply), which aims to standardize fast charging technology, successfully compiled Qualcomm QC4.0, and reached a consensus with the Thai Laboratories of the Ministry of Industry and Information Technology. It is expected to be unified with the national standard.
