VOOC flash charge is a unique low-voltage high-current fast charging protocol of OPPO mobile phones, which has been developed to VOOC4.0, supporting 5V2A and 5V6A output, maximum 30W fast charging power, and also compatible with other VOOC fast charging protocols. VOOC4.0 can charge a 4025mAh battery to 50% in 20 minutes, fully charged in 55 minutes, and the charging process has almost no temperature rise, the experience is very good, compared to PD fast charging, it can be said that it is still very competitive.
OPPO Reno3 Pro 5G uses VOOC4.0 charger for fast charging, charging current up to 5.63A.
Charging head network learned that the INDUSTRY WELL-KNOWN FAST CHARGING CHIP ORIGINAL MANUFACTURER ZHUHAI ZHIRONG LAUNCHED SW2327 on September 10, 2021 officially obtained the Thiel Certification Center VOOC4.0 product certification, certificate number 0302147161325R0M. Thiel Certification Center is the only authorized certification laboratory for OPPO VOOC fast charging protocol. It is worth mentioning that the SW2327 protocol chip not only supports VOOC4.0, but also supports the UFCS converged fast charging specification.
Zhirong USB Type-C fast charging protocol chip SW2327 officially passed VOOC4.0 certification, and the certificate is valid until September 9, 2024.
Zhirong SW2327 is a highly integrated and high-performance USB-C/USB-A interface chip with a built-in ARM Cortex-M0 core with a 40MHz frequency and a maximum operating frequency of 40MHz. Built-in support for 10K flashing 64KB car grade eFlash + 4KB memory. With I2C master-slave interface, it can form a digital voltage regulating charger and mobile power supply with PI InnoSwitch3-Pro and I2C interface buck-boost controller, with higher integration and better reliability.
Zhirong SW2327 supports 3-30V input voltage range, the chip supports optocoupler feedback, I2C feedback, and FB pin feedback, supporting chargers, power banks and car charging applications. The chip has built-in complete and rich protection functions, which can ensure the maximum security of the system from being damaged. The SW2327 simplifies multi-port charger power distribution design by configuring the chip's maximum output power and reduced output power through three pins.
The picture shows the InnoSwitch3-Pro protocol chip connected to the PI through I2C, which realizes a simplified and efficient USB PD fast charging design. At the same time, the I2C interface can be combined with the synchronous buck-boost controllers of Nanxin, Zhirong and other manufacturers to achieve high-power mobile power supply and vehicle charging design compatible with multi-fast charging protocol.
Charging head net summary
