Disassembly report: Beisi 100W 2a2c gallium nitride fast charging socket

2022-05-04

Presumably, many friends have encountered that after buying a notebook, they want to buy another power supply. They can put one at home and one at the company. They can carry the computer every day without carrying a charger, which can reduce the weight of the backpack. They can also carry only a small bag with a notebook, which is very convenient. But in the past, the notebook power supply was complex. Notebooks of the same brand had a variety of interfaces, and buying the wrong thing happened from time to time.

The introduction of USB PD fast charging has greatly improved the compatibility of notebook chargers. No matter what brand, as long as it has usb-c interface to charge, it can use USB PD chargers of other brands to charge, which greatly reduces the trouble of purchasing chargers.

Beisi has launched a plug-in board that supports 100W power output, which is very suitable for users who purchase an additional power supply after purchasing a laptop. The size of the patch panel is about the same as that of the traditional adapter. It can not only supply power to the notebook, but also connect other household appliances, which is convenient to use.

Beisi 100W gallium nitride fast charging socket is equipped with a 1.5m long extension cable to meet the daily expansion use. There are 2 + 3 AC sockets on both sides of the socket, supporting 2500W power. It is also excellent to use the built-in 100W USB PD fast charge to charge the notebook, connect a monitor and plug in a hot kettle.

Through the disassembly of the charging head network, it is learned that the glue filling process is adopted for the internal fast charging module of Beisi socket, which can enhance the heat dissipation performance, improve the weather resistance and improve the protection performance, effectively avoid the accidental drop and damage of the patch panel in the process of use, and make it more durable. The internal fast charging module of the socket adopts NXP tea2016aat + tea1995 PFC + LLC + synchronous rectification scheme with constant voltage output, which is welded into a whole by five small plates.

PFC uses nano micro semiconductor nv6127 with Tyco Tianrun silicon carbide diode. LLC switch tube is from Huarui micro, synchronous rectifier tube is from Huayi micro, primary filter capacitor is from kaizexin, and synchronous rectifier output and secondary step-down output filter solid-state capacitors are from Fengbin. The three-way independent step-down of the module adopts Zhirong sw3516h step-down scheme, which has good fast charging compatibility and can meet the high-power charging of notebooks and mobile phones.
