Huawei Wireless Charger (15W wireless Fast filling version) supports dual-mode working mode, dual-mode automatic switching. Charging Apple iphone using fixed frequency voltage regulation mode, support 7.5W wireless fast charge;
To Huawei Mate20 Pro charging using frequency conversion mode of operation, support 15W wireless fast charge.
Second, Huawei Wireless Charger (15W wireless Fast filling version) disassembly The panel and the base are fixed by dispensing method to ensure the reliability of the connection between the two.
Pry open the panel to reveal internal components.
Upper cover affixed aviation grade heat dissipation material PCM, phase change energy storage, greatly extend the temperature rise time.
The main structure is fixed to the base with 2 screws.
Remove the screws, the coil and the aluminum alloy under the frame for the PCB board. The aluminum alloy frame and the base are filled with thermal conductive silicone grease, which can radiate the heat out in time and fully.
The top is a light guide and a shading cotton.
Remove the 3 screws on the PCB and remove the main parts. Silicone heat is available on the PCB with a larger heating component.
The launch coil adopts the WPC Qi A11 standard Coil, and the solder joints at the junction of the coil and the PCB pad are rounded and full.
Clean up the silicone on the PCB components.
There are no components on the back of the PCB.
Using the United States IDT P9242 highly integrated 15W wireless charging transmitter chip, support foreign body detection (FOD) input voltage range 4.25v-21v, in line with WPC1.2 standards, built-in temperature protection, support programming led mode.
IDT IDTP9242 specification Book. Screen printing bzn, TI TPS73701 voltage regulator chip, the main control chip voltage stabilizer power supply.
Next to the 8.0000MHz passive crystal. Bottom for over-hole welding fully shielded usb-c, screen printing L807241, from the vertical news precision. Screen printing 7d530l, Nexperia semiconductor psmn7r5-30mld. Wireless Charging switch tube, pressure-resistant 30V, 7.5mω, logic level driven nMOS.
A total of 4 PSMN7R5 MOS tubes are used to form the H bridge.
Psmn7r5-30mld detailed information.
A number of MLCC capacitors are used, including 4 NPO capacitors.
Dismantling the family photo.
Third, the charging head network disassembly summary Huawei Wireless Charger (15W wireless Fast charging version), the use of IDT P9242 wireless charge transmitter chip, for 15W wireless charging to provide protection. Upper cover affixed aviation grade heat dissipation material PCM, phase change energy storage, greatly extend the temperature rise time, with coil under the large aluminum heat sink and PCBA below the heat dissipation paste, so that fast charge time longer, faster charging.
Material workmanship is solid, value for money. Huawei 15W Wireless Fast Charger Disassembly: value for money
