In the process of vigorous development of the gallium nitride fast charging market, multi-port chargers have always played a very important role, especially in high-power fast charging source products, multi-port chargers have great advantages, both can achieve full speed fast charging when single-port output, and can also achieve intelligent power distribution when multiple devices are charged at the same time, so that the performance of high-power chargers can be fully utilized.
In order to reduce the burden of the user's backpack, the major 3C brands have made efforts in the multi-port charger market, aiming that users can go out with a charger to solve the charging problem of all devices.
Zhirong pioneered dynamic control multi-port multi-protocol fast charging technology
Speaking of multi-port fast charging, we have to mention Zhirong Technology, which is mainly because of its pioneering dynamic control multi-port multi-protocol fast charging technology, a chip can achieve dual output control, through the combination of multiple chips, it can achieve multiple independent fast charging output, which is the best partner for high-power fast charging.
When developing a multi-port fast charge charger, the AC-DC power supply part first outputs a fixed voltage, and then the secondary side is completed by the multi-port fast charge chip of Zhirong to complete the secondary buck and protocol identification. With the coordination of external MCUs, multiple outputs can be realized in a very streamlined circuit, and intelligent power distribution can be achieved to meet the full power output of any single port and the simultaneous output of multiple ports, which not only improves the user experience, but also controls the volume and production cost of the product.
As can be seen through the circuit block diagram, when using a multi-port fast charging chip of Zhirong, 3 chips can be saved compared with the traditional solution. Zhirong chip 1 top 4, greatly simplified the circuit design of multi-port fast charger, easy product development.
Zhirong launched 11 multi-port fast charging chips
It is understood that for the application of the multi-port fast charging market, Zhirong has launched 11 fast charging chips, the power ranges from 30W-140W, divided into two types of built-in MOS and external MOS, by selecting different chips, you can achieve single A port, single C port, double A port, double C port and A + C port and other interface control.
Zhirong's multi-port fast charge chip is integrated with synchronous buck controller and fast charge protocol recognition function, some of which are integrated buck MOS, a chip plus an inductor and a small number of peripheral devices can achieve output control, greatly simplifying the circuit, is conducive to the development of small volume fast charging source.
For 30W fast charging applications, Zhirong launched SW3515, SW3517, SW3519, SW3521, SW3522 four chips, of which SW3515, SW3517 and SW351 can meet the design needs of 1A1C or dual A-port fast charging, SW3521 and SW3522 are chips specifically for single interface output, which is extremely cost-effective.
For 60W fast charging applications, Zhirong SW3526 can meet the needs. It adopts two external MOS design, supports single A port or single C port output control, flexible application.
100W multi-port fast charging application is the best play of Zhirong, and its SW3516 series and SW3518 series have a wide range of applications in multi-port fast chargers, and have accumulated a good reputation.
For the higher power charging market, the two chips of Zhirong SW3536 and SW3556 can support up to 140W charging, which is used for fast charging applications of 1A1C and dual C ports, respectively.
It is worth mentioning that SW3616S became the first fast charging chip with a built-in protocol to obtain USB PD3.0 certification. In addition, Zhirong Technology has also cooperated closely with OPPO to launch VOOC-certified car charging chips SW3518S, SW3519S and SW3523.
Application case of Zhirong multi-port fast charging chip
With the large-scale commercial use of gallium nitride fast charging technology, 65W gallium nitride multi-port charger has become a must-have product for almost all accessory manufacturers, which has also accelerated the large-scale commercial use of Zhirong multi-port fast charging chips. Based on the high-frequency QR flyback topology architecture, the power supply manufacturer greatly reduces the internal AC-DC power supply volume of the charger, and the multi-port output part selects the Zhirong secondary buck chip, which also simplifies the circuit and reduces the occupation of the internal space of the charger.
In addition, in the 100-watt high-power Gallium nitride fast charging market, the advantages of LLC architecture and SiC silicon carbide diodes are also very obvious. However, due to the fast charging source developed based on the LLC architecture, it can only fix the voltage output and cannot meet the wide voltage output of USB PD, which also provides an opportunity for the development of the multi-port fast charging chip of Zhirong Technology. PFC + LLC architecture + secondary buck, you can easily complete the design of high-performance multi-port fast charging source, and thus become the mainstream choice of 100-watt fast charging.
