2024-09-02
In the second half of last year, ugreen, a well-known 3C accessories brand, launched a number of fast charging accessories at one go. One of them is the 65W gallium nitride fast charging charger CD244, which costs 128 yuan. Recently, charging head network got the white version of this charger.
As for the seemingly "repeated" phase I disassembly this time, it's not because of the different colors, but because the editor learned that the white version uses the PI scheme of a well-known power supply manufacturer, so it's still worth opening it. Now let's learn more about the internal situation of the charger with Xiaobian.
The 65W gallium nitride charger of lvlian adopts a fresh white design, which is still a long columnar shape, small and portable. The unique appearance design of rounded corners and sections makes the product unique. The charger is equipped with folding pins, which is easy to carry. With 2c1a output interface, it supports 65W PD fast charging and 3.3-21v 3A PPS fast charging. It supports the fast charging of Android phones very well.
Through disassembly, the charging head network learned that lvlian charger has built-in two PI highly integrated master chips, together with two transformers, one large and one small, to form two switching power supplies. The output protocol chip uses the British chipset ip2738 for three port protocol control, and uses the Weizhao semiconductor MOS tube for two-way switching power supply output in parallel and interface control, which is different from the previous secondary step-down scheme.
The charger uses Fengbin electrolytic capacitor and emerald solid-state capacitor for filtering, the rectifier bridge and power chip cover the heat sink for heat dissipation, and the internal glue filling enhances heat dissipation. The overall design and materials are very reliable.
