Previously, the charging head network shared with you the disassembly of a Motorola Australian standard plug 30W fast charger, in fact, this charger also has an English version. The overall style of the two versions of the charger is the same, both support PD3.0 and PPS fast charging protocol, only the pin difference is obvious.
Although intuitively many people may think in their hearts "is not to change a plug", in fact, the charging head network has encountered many similar cases before, the appearance does not look like a big difference, but the program is completely different. The following is to disassemble Motorola's British 30W charger to see if it is in that situation.
It is worth mentioning that the recent charging head network has also disassembled the Motorola Edge X30 mobile phone standard 68W Gallium nitride charger, welcome to check.
First, the appearance of Motorola 30W charger
The charger adopts a pure black PC material shell, the surface is matte, the waist is transitioned and rounded on all sides, and the overall shape is classic.
The front of the fuselage is designed with the Motorola brand logo.
On the other side, there are 30 words, but the number 0 is only half, and the design is very distinctive.
The charger is equipped with English plugs.
Charger parameters are printed on the input housing
Model: MC-303
Input: 100-240V~50/60HZ 0.9A
Output: 5V3A, 9V3A, 10V3A
The product has passed CE certification, as well as Level VI energy efficiency certification.
The top surface is equipped with a single USB-C interface, centered design, and the black rubber core does not expose copper.
The measured height of the charger body was 61.21mm.
The width is 41.83mm.
The thickness is 27.79mm.
Compared with the Apple 30W charger, the main body of Motorola is smaller.
Net weight is approximately 81g.
The USB-C port was measured by using the Chargelab POWER-Z KT002 to support PD3.0 and PPS fast charging protocols.
And with 5V3A, 9V3A, 10V3A three sets of fixed voltage gears, as well as 3.3-11V3A a set of PPS voltage gears.
Second, motorola 30W charger disassembly
The shell is removed by brute force cutting.
The measured module length was 47.51mm.
The width is 38.04mm.
The thickness is 22.07mm.
The front of the motherboard capacitors, transformers and other devices are glued and reinforced.
The back of the board is covered with insulating plastic plates and heat sinks.
Remove the reverse to see the rectifier bridge, PI switching power supply main control chip and synchronous rectifier tube on the back.
Through observation, it was found that this charger adopts the QR switching power supply architecture, and the protocol chip controls the output voltage of the interface. Let's start with the inputs to understand the information of each device.
At a glance of the inputs, some of the devices are insulated.
Fuse close-up.
NTC surge suppression resistors are used to suppress up-power inrush currents.
Common mode inductors are two-wire wound for filtering out EMI interference.
Close-up of FMB30M rectifier bridge.
I-beam inductive jacket insulated tube.
Two high voltage filter electrolytic capacitors from Chengxing are available in 400V 18μF and 400V 27μF.
The main control chip power supply capacitor is also from Chengxing, and the specification is 50V 10μF.
Switching power supply main control chip for SC1711C, PI custom part number, belongs to the InnoSwitch3-Pro series, built-in PWM master control, high voltage MOS and synchronous rectifier controller, the integration degree is very high.
Transformer close-up.
Y capacitance close-up.
Synchronous rectification MOS from Visco Semiconductor, model VSO009N06MS-G, NMOS, withstand voltage 60V.
Wei Zhao VSO009N06MS-G Details.
Charging head network disassembly learned that Weizhao MOS tube is widely used in chargers, wireless charging, car charging, charging treasure, energy storage power supply and other aspects, and has been huawei, xiaomi, zimi, Samsung, OPPO, VIVO, Meizu, Nubia, Beth, Bull, NetEase intelligent manufacturing and other well-known brands of dozens of products to adopt, product quality has been unanimously recognized by customers.
At a glance at the output, the USB-C female seat is soldered vertically, and there are solid capacitors and protocol chips on both sides.
Two close-ups of solid capacitors, both 16V 470μF.
The USB PD protocol chip adopts Weiyi WT6635P, supports QC4+ and PPS fast charging protocols, and soP10 package.

USB-C female close-up.
All disassembled, let's take a family portrait.
Charging head net disassembly summary
Through the actual disassembly, it also verified the statement at the beginning of the small editor, motorola's British standard 30W fast charger compared to the Australian standard version, indeed uses a completely different fast charging program.
Disassembly found that this charger uses PI InnoSwitch3-Pro series chip SC1711C, and Weizhao synchronous rectifier VSO009N06MS-G to form a switching power supply, weiyi WT6635P through the protocol to identify the control interface output voltage. The overall material workmanship is still solid and reliable, and has good reference value.
