Take the first place again! Yingjixin ip5318a passed the certification of Qualcomm qc3.0

Yingjixin ip5318 adopts fast charging all in one fully integrated SoC technology. The application of this technology not only realizes high-performance charging and discharging experience, but also has competitive market price. As early as April 18 this year, SMIC ip5318 passed the certification of Qualcomm quick charge 2.0, becoming the first single-chip SOC in the mobile power charging chip industry to pass the certification, setting off a storm of popularization of fast charging mobile power supply.

Subsequently, SMIC upgraded ip5318 again. Ip5318a supports the latest quick charge 3.0 technology of Qualcomm, and got the certificate on July 27. With the unique design concept of single-chip SOC, it has become the only mobile power solution with quick charge 2.0 and quick charge 3.0 certification in this field. In order to facilitate customers to pass the latest certification of Qualcomm, SMIC CEO Huang Hongwei updated in the wechat circle of friends that the only fully integrated mobile power SOC certified by Qualcomm qc3.0 is yingjixin ip5318. With 5318, the whole mobile power supply can easily pass the high pass qc3.0 certification. We also provide special certification guidance. Protocol IC is very painful. The era of authentication will end soon.

Yingjixin ip5318a is a power management SOC integrated with type-C protocol, quick charge 3.0 output fast charging protocol (compatible with DCP identification function, compatible with bc1.2, apple and Samsung mobile phones), Synchronous Boost converter, lithium battery charging management, battery power indication and other multi-functional power management SOC, providing a complete power solution for mobile power supply. With high integration and rich functions, only one inductor is needed to realize the step-down and boost function, so that it only needs a few peripheral devices in application, and effectively reduces the size of the overall scheme and reduces the cost of BOM. The synchronous switch boost system can support quick charge 3.0, provide maximum output capacity of 18W and conversion efficiency of 96%.

The intelligent negotiation for optimal voltage (inov) algorithm is first used by Qualcomm quick charge 3.0 in similar products. Inov is a new algorithm developed by Qualcomm technologies to help portable devices have the ability to select the required power level to achieve optimal power transmission at any time and maximize efficiency.

Compared with the high pass quick charge 2.0, which provides 5V, 9V, 12V and 20V charging voltage, quick charge 3.0 provides a flexible choice of voltage from 3.6V to 20V in 200mV increment. This will allow the phone to obtain the right voltage to achieve the desired charging current, thereby minimizing power loss, improving charging efficiency and improving thermal performance.

According to the Meizu m8e disassembly report provided by the charging head network, yingjixin products have successfully entered the Meizu system; in addition, yingjixin is also actively cooperating with Samsung to obtain the AFC fast charging agreement; and from the information obtained from the supply chain, mobile phone brands such as LETV, Xiaomi, Huawei and Samsung are also evaluating and testing Ying Jixin products. In the second half of this year, you will see more in the first-line mobile power brands Duoying's figure is the core.
