According to the report from the charging head network industry, mobile phone manufacturers are currently actively entering the gallium nitride fast charging market, of which Huawei, Xiaomi, OPPO, realme, Samsung, Nubia, Meizu and other well-known mobile phone companies have successively released and launched gallium nitride chargers based on mobile phones and laptop fast charging. At the same time, 17 major e-commerce brands have also released dozens of gallium nitride fast charging products.
The popularity of gallium nitride and USB PD fast charging has effectively alleviated the problem of insufficient battery life of electronic devices, and the rapid charging experience brought by high power has also been praised by the majority of users. However, with the increase of electronic products in the hands of users, the original single-port charger has been unable to meet the needs of multi-device simultaneous charging, and the charger with USB PD fast charging and multi-port output has become the user's just need, and the market is growing.
According to the design scheme of the traditional multi-port charger, if you need to achieve fast charging, either multiple transformers are built-in and made into a completely independent ac-DC architecture, or a transformer is shared, and then the secondary side uses multiple buck chips and protocol chips. However, these two designs are not only expensive, but also have a large number of components, which is not convenient for miniaturization of the product.
In response to this market pain point, Zhuhai Zhirong Technology Co., Ltd. launched a new set of multi-port USB PD fast charger design ideas. And with the characteristics of small size, multi-protocol, high cost performance, etc., it has become one of the mainstream multi-port fast charging solutions in one fell swoop, and has been adopted by dozens of power products of many brands such as Bess, Beijing Tokyo, Green Giant Energy, hyper JUICE and so on.
First, Zhirong launched 8 USB PD multi-port fast charger chips
In the field of USB PD multi-port fast charging, Zhirong has launched a total of SW3510, SW3516, SW3517, SW3518, SW3519, SW3521, SW3522, SW3526 eight fast charging chips, all of which adopt a highly integrated design, built-in synchronous buck control and fast charge protocol recognition and other functions.
Among them, SW3510, SW3516, SW3518 can achieve a maximum of 100W fast charge output by matching external MOS tubes; while SW3517, SW3519 and SW3526 have built-in synchronous buck MOS tubes, the chip integration is higher, the periphery is more streamlined, and it is more suitable for the design of miniaturized multi-port fast charge chargers; SW3521 and SW3522 are the controllers developed by Zhirong for three-port fast charge chargers, which have great cost advantages in the development of three-port fast charge chargers.
It is worth mentioning that Zhirong SW3518 and SW3519 have both obtained VOOC flash charging certification, which can assist power supply manufacturers in developing VOOC certified high-performance multi-port fast charging products.
Compared with the traditional secondary buck scheme, the biggest difference between the Zhirong multi-port USB PD fast charging scheme is that the traditional scheme needs to complete two differentiations in the AC-DC part, which requires two synchronous buck controllers and two protocol chips. The zhirong solution is to integrate the synchronous buck controller and protocol recognition into a chip, which realizes the fast charging of single-port output and the intelligent power reduction of dual-port output; it can not only meet the needs of multi-device charging, but also achieve excellent cost performance.
In addition, based on the above chips, Zhirong has also developed a complete fast charging solution such as the reference design of the 18W dual-port USB PD fast charge charger, the reference design of the 60W dual-port USB PD fast charger, the reference design of the 69W three-port USB PD fast charger, the reference design of the 45W ultra-small gallium nitride supercharge, the reference design of the 87.5W hybrid gallium nitride supercharge, etc., to meet the application needs of customers in an all-round way.
