Not long ago, the charging head network disassembled ugreen's 100W four port Gan fast charging CD226. Recently, ugreen has launched a 100W desktop charging CD226 for the scene of simultaneous charging of desktop and office devices. It is not only equipped with 3c1a four interfaces, but also equipped with CD226.This charger not only supports up to 100W fast charging, but also meets the demand of mobile phone, tablet and two laptops for fast charging at the same time, solving the problem of insufficient charging efficiency of multiple devices. The product supports 5A PPS fast charging and has good compatibility. The detailed evaluation report has proved this point. Next, we will disassemble this desktop charger and take a further look at the materials and workmanship.Ugreen green link's 100W 3c1a four port desktop charger has a square and flat body, and the top surface is processed with laser texture technology, which increases the feel and aesthetic feeling. It is equipped with a 1.6m power line and a 1m 100 watt CC line, which completely solves the pain points of inconvenient wall insertion and long distance. The product supports 18w-100w fast charging to achieve full power coverage, and supports charging up to four devices, which can still maintain fast charging. It can solve the charging problem well whether it is playing games in teams or using multiple devices in the office.Through the disassembly of the charging head network, it is learned that the charger adopts PFC boost plus three-way switching power supply circuit design, which is independent of each other and does not interfere with each other, so that it can support the fast charging of multiple devices at the same time without reducing the power, and at the same time, it can avoid the disconnection and restart of multi port charging at the same time.The controller of PFC boost circuit adopts NXP tea19162t and mepson msm065g1 silicon carbide diode rectifier. Built in three-way switching power supply, two of which use the PI sc1738c scheme for usb-c1 and C2 power supply, one uses the PI in3268c scheme for usb-c3 and a port power supply, with high integration. The output terminal uses three British core ip2726 protocol chips to control the four port output voltage and output power intelligent distribution. The matching MOS transistor mainly comes from the new power, and the overall scheme is very reliable. The output end uses Yongming small volume fast charging special solid-state capacitor for filtering.
