Disassembly report: Lenovo Yoga 65W double C-Port Gan charger

2021-05-06

Many people may be familiar with Lenovo, but they don't know it's Lenovo's brand just by saying Xiaoxin, yoga, ThinkPad, Savior and so on. In recent years, these brands continue to launch a variety of popular products to meet the needs of different users. In terms of accessories, Lenovo Yoga recently released cc65 dual port Gan charger.

The charger is made of the third generation of Gan power devices. The initial price is 119 yuan. It is equipped with a 1.5m long 100W fast charging CC line as standard. The charger body is small and refined, and is equipped with two usb-c interfaces to meet the fast charging requirements of two devices at the same time. Next, the charging head network will disassemble this new product in detail, so as to further understand the design and materials of the product.

At present, the charging head network has disassembled many kinds of Gan fast charging power supplies, such as ThinkPlus 65W Gan lipstick power supply, ThinkPlus 65W Gan lipstick power supply pro, Lenovo 90W flash charging dual port Gan charger, etc. you can click the blue font to view more disassembly reports.

Lenovo yoga cc65 dual port Gan charger has a smooth and simple body, round corners, foldable pins and dual C output ports, and power density of 0.88w/cm ³, The whole is very small. The C1 and C2 ports support the maximum 65W / 45W and 18W fast charging respectively. Depending on the input voltage, they support QC, PD and PPS universal fast charging protocols, and support 45W + 18W dual port simultaneous fast charging strategy to meet the demand of simultaneous fast charging for laptops and mobile phones.

Through the disassembly of the charging head network, we learned that there are four small boards on the main board of this charger to make full use of the internal space, and there are common designs such as isolation board and heat sink. The charger switch power supply has a wide range of output, which is composed of Anson ncp1342 with nano micro nv6134 Gan power chip, and MPs mp6908a with Infineon synchronous rectifier. The two C ports of the output terminal are controlled by the IP 2726 protocol chip, the C1 port is directly output, and the C2 port circuit is converted by sc8721. C port has TVs for static protection.

This kind of charging head can make the volume so small in the case of dual port configuration, which is mainly due to the use of nano micro semiconductor ganfast chip. Nv6134 is the third generation of nano micro Gan power chip, which not only has the advantage of volume for the charger, but also has very good performance in temperature, conversion efficiency and other aspects.
