Charging head net disassembly summary
ELIXAGE This charger is a product launched in 2019, and the output of 14.5V2A specifications is the same as Apple's 29W USB PD charger. Compared with the traditional style of Apple's original charger, this charger's unique color matching design plus brand logo has a highly recognizable shell design.
The charger adopts a two-circuit board design inside, the switching power supply circuit is on a separate PCB, and the output USB-C matrix and protocol chip are soldered on a vertical small board, which fits the housing design. Internally, on-premise OB2632 is matched with MPS MP6908 synchronous rectifier controller, the primary switch tube is from Pingwei, and the synchronous rectifier tube is from Zhenmaojia. The output voltage is controlled by Infineon's CYPD3174.
