Disassembly report: lvlian 200W 4c2a six port gallium nitride desktop charger

2023-08-08

With the popularity of notebook and high-power mobile power PD fast charging, there are also many types of high-power chargers for consumers to choose from. However, the use of multiple single port 100 watt chargers at the same time takes up too much row space. When connecting multiple devices, the output power of the 100 watt multi port charger cannot reach the extremely fast charging experience. In short, it is very tangled.

In order to meet the demand of fast charging of high-power devices at the same time, lvlian has launched a 200W high-power gallium nitride multi port charger, which has four usb-c ports and two usb-a ports, of which two usb-c ports support 100 watt output, and the two ports can be connected arbitrarily, which can provide two 100 Watt output, which can charge the notebook at full speed, and the function is very powerful.

Charging head network has got the 200W charger of lvlian. Now let's disassemble it to see what materials and designs are used inside this big Mac charger. Let's have a preview.

The 200W gallium nitride desktop charger launched by lvlian has strong performance. Two usb-c1 and usb-c2 support 100W power output, which can simultaneously charge two notebooks at full speed. Its 4c+2a combination meets the power configuration of the office desktop, and fully charges mobile phones, laptop computers and mobile power supplies. It can be called a new generation of universal charger.

The charging head network learned through disassembly that the 200W gallium nitride charger of lvlian adopts pfc+llc switching power supply architecture, and the switching power supply scheme adopts NXP tea8918bat two in one controller with tea1995 synchronous rectifier controller. PFC and LLC use four inn650d260a gallium nitride power devices from innoseco, together with Pingwei silicon carbide diodes and synchronous rectifiers.

DC-DC step-down adopts five independent step-down circuits. Zhirong sw3516h is used for step-down output, and Neusoft carrier single chip microcomputer is used for intelligent power distribution. Aishi electrolytic capacitor and Fengbin solid-state capacitor are used inside the power supply. The upper and lower sides of PCBA module are covered with heat sinks, and the heating elements are dissipated through large-area heat sinks to ensure stable use. The internal materials and design are solid and reliable.
