Release date：2019-02-24   Views：2031

Nanxin recently launched sc2001 fast charging protocol chip, supporting pd2.0 / pd3.0, PPS, SCP, FCP, AFC, vooc and other fast charging functions

In November last year, oppo held the supervooc open day in Shanghai. The charging head network was invited to participate in the activity. It was learned from the scene that oppo officially announced the opening of patent authorization for vooc flash charging. It is reported that oppo also authorized the third-party accessories to be certified by the authority of Tel laboratory. On site, oppo also announced the list of partners, and Shanghai Nanxin Semiconductor Technology Co., Ltd., a well-known domestic power supply company, became the first batch of authorized chip manufacturers.

Sc2001 flash charging protocol chip of Nanxin has successfully passed the official vooc certification of oppo, and obtained the authoritative test report of Tel laboratory. It is reported that sc2001 is an independent vooc flash charging protocol chip, which supports oppo's latest supervooc, i.e., 10V, 5A, 50W flash charging; it is also compatible with the previous generation of vooc, 5V, 4A and 20W flash charging. This is also the first fast charging chip officially shipped with supervooc authorization in 2019. It can be seen that Nanxin's R & D strength in this field has been recognized by oppo.

Nanxin sc2001 is suitable for mobile power supply, charger, car charger and multi port charger. In addition, Nanxin not only owns the vooc flash charging protocol chip authorized by oppo, but also has a wide range of voltage up and down chip models. It has become a representative of this field in domestic power chips, and has been selected by many well-known brands in the industry. It has designed fast charging mobile power supply, charger and other products for bulk delivery. Among them, oppo's picachu flash charging mobile power supply uses the South core buck chip.

At present, the annual sales volume of oppo mobile phones is over 100 million, and the market share of vooc flash charging mobile phones is quite large. Besides the official brand of oppo, there are basically no other third-party authorized brand products to purchase.

Oppo officially announced the opening of the patent authorization of vooc flash charging, which is undoubtedly a significant benefit for relevant parts manufacturers and upstream chip and component suppliers. The official delivery of sc2001, a protocol chip for South core's vooc flash charging protocol, will help the third-party vooc flash charging accessories to the market. For the majority of consumers, it will be able to buy more affordable and more diverse types of vooc flash charging power products.

Vooc flash charging is a fast charging technology with independent intellectual property rights launched by oppo in 2014. The technology uses a special vooc flash charging adapter and a special microusb / usb-c data cable to charge the mobile phone with 5V / 4A voltage and current. Due to the use of direct battery charging, the efficiency is higher, which can effectively reduce the heating of mobile phone charging.

In recent years, vooc flash charging has been constantly evolving. In 2018, oppo brought supervooc super flash charging with the help of Lamborghini special version find x, with the charging power upgraded to an amazing 50W (10V / 5A).

According to the latest statistics of charging head network in November 2018, there are up to 25 oppo mobile phones supporting vooc flash charging, and 3 mobile phones supporting supervooc super flash charging have been launched in succession. With the increasing sales of oppo mobile phones, the market share is getting higher and higher, and the vooc flash charging has attracted more and more attention.
