At present, Zhirong is in a period of rapid development, and has a number of product lines in mass production, especially in the field of fast charging has become a leading chip supplier.
As a technology company committed to providing high-performance power chip solutions for the industry, Zhirong Technology has won the national high-tech enterprise certification less than two years after its establishment, which shows the deep accumulation of integrated circuit design patents.
In 2020, Zhirong Technology's latest USB PD fast charging protocol chip SW230x series has successively obtained Qualcomm QC4+ certification and USB PD3.0 fast charging certification, and has successively achieved mass production.
From independent protocol chips to power protocol fully integrated SoC chips, from the accessories market to the mobile phone PC and other terminal product markets, Zhirong Technology has launched a full range of applicable chips, and cooperative customers include Huawei, OPPO, Qualcomm, Bull, ZTE, Lenovo and other well-known enterprises.
Starting from fast charging, Zhirong is determined to develop into the industry's top comprehensive analog chip company.
Second, Zhirong pioneered multi-port fast charging power intelligent distribution technology
With the increase of electronic equipment in the hands of users, the market demand for multi-port fast charging accessories is increasing, and in the traditional multi-port charger, either it is impossible to achieve the fast charging function, or the product volume is too large, inconvenient to carry, and the internal structure design is very complex and the cost is high.
In order to solve this market pain point, Zhirong pioneered the intelligent distribution technology of multi-port fast charging power in the industry. When used to develop a multi-port fast charger, the AC-DC circuit outputs a fixed voltage, and then completes the secondary step-down through the Zhirong High integrated chip, so as to achieve the characteristics of any single-port output can be full power, multi-port simultaneous work intelligent power reduction, taking into account the user experience, product volume, production costs, etc.
In addition, compared with the secondary buck circuit of friends on the market, Zhirong's multi-port fast charge power intelligent distribution scheme also has great advantages. Taking the development of a dual-port fast charger as an example, the friendly business solution needs to use two buck chips and two protocol chips after the AC-DC switching power supply to achieve; if the smart solution is used, only a high-integration chip is required to complete the above functions without changing the AC-DC switching power supply, which greatly reduces the number of chips, which is conducive to reducing the volume of the charger and reducing the COST of the BOM, achieving the ultimate cost performance.
