Disassembly report: mcdodo mcdodoo 30W 1a1c USB PD fast charging charger

Before that, the charging head network shared with you the disassembly of mcdodo's 18W USB PD fast charging charger, and learned that it adopts a full set of domestic IC scheme, which is highly integrated. Recently, mcdodo launched a USB PD fast charging charger for the 30W market, and adopted the 1a1c dual port design.

It is worth mentioning that in addition to the excellent protocol compatibility, the AC pin of this charger also adopts a replaceable design, and comes with several versions of pins, which makes the pin compatibility better. Even if you travel abroad, you don't need to worry about the problem that the pins are not compatible and can't be used. The following charging head network will bring you the detailed disassembly of this product.

1、 Appearance of mcdodo 30W 1a1c fast charging charger

Mcdodo 30W 1a1c USB PD charger is packaged in white box with hook design for offline display. Printed on the front of the product appearance and conversion pin design, product name: 30W PD travel charger. The back of the packaging box is printed with pictures of the use scene of the product and relevant product information. In addition to the charger, there are two AC pins of different specifications.

The additional AC pins are the British version and the European version.

The main body of the charger adopts a white shell, and the surface is matte, so it is not easy to be scratched during use; The overall shape is too long, and the brand logo of the product is printed on the front.

The output end panel is designed to sink and is equipped with two output interfaces. The usb-c interface is marked with PD, and the usb-a interface is marked with QC and SCP.



The input pin is foldable and easy to store, with detailed specifications printed on the side of the pin. Product model: tc-095pq; Input: 100-240V ~ 50 / 60Hz 0.8A; Usb-c single port output: 5V / 3a, 9V / 3a, 12V / 2.5A, 15V / 2a, 20V / 1.5A and 3.3-11v/3a; Usb-a single port output: 4.5v/5a, 5V / 4.5a, 9V / 3a, 12V / 2.5A, 20V / 1.5A. Usb-a interface and usb-c interface output; 5V/4.8A。 At the same time, this product has also passed the FCC, ETL certification, and meets the VI level energy efficiency standards.

Because this charger is mainly aimed at overseas market, it is equipped with American standard pins as standard, and it can also be compatible with China's electricity standard.

The charger's pin adopts special structure design, and the attached European standard pin can easily replace the original pin specification.

The pin of British standard can also be replaced, so as to charge the equipment when traveling abroad.

The net weight of the charger is about 75g, which is relatively light. As a 30W 1a1c dual port fast charging charger, mcdodo's product is smaller, only slightly larger than Apple's 18W charger.

The output protocol of charger usb-a port is detected by using chargerlab power-z kt001. The display supports apple 2.4a, USB DCP protocol, qc2.0, qc3.0, FCP, AFC, SCP and other mainstream fast charging protocols.

The protocol support of usb-c interface is consistent with that of usb-a interface, and it is compatible with apple 2.4a, USB DCP, qc2.0, qc3.0, FCP, AFC, SCP and other mainstream protocols.

In addition, usb-c interface also supports USB pd3.0 PPS fast charging protocol, in which the fixed voltage output gears are 5V / 2.4a, 9V / 3a, 12V / 2.5A, 15V / 2a and 20V / 1.5A; PPS voltage range is 3.3-5.9v/3a and 3.3-11v/3a.

2、 Mcdodo 30W 1a1c quick charging charger is disassembled, and the shell is opened from the pin side of the charger, and the AC pin is connected to the PCB board with two silica gel wires.

Take out the internal PCBA module, it can be seen that the transformer is arranged in the middle, the peripheral gap is fixed with silica gel, and the position close to the secondary side output interface is isolated with plastic insulation board.



Summary of dismantling charging head net

iPhone Charger Adapter

Mcdodo 30W 1a1c USB PD fast charging charger is simple in appearance design. The standard American Standard pin is foldable, which is convenient for storage and carrying. At the same time, AC pin can be changed to different standards according to the needs of users, which is suitable for many countries and regions with municipal power standards. The 30W output power of usb-c port can not only meet the charging of mobile phones and mobile power supply, but also for iPad and small power notebook computers. It is widely used. At the same time, the usb-a port supports 22.5w fast charging, which is very friendly to Huawei's low-voltage and high current fast charging mobile phones.

It is learned from the disassembly of the charging head network that this charger has a full set of domestic control chips built in. The main control chip of the charger, the Sloan sdh8666q, adopts a built-in MOS design, which has a very high degree of integration and does not need heat sink; The secondary adopts the synchronous rectifier circuit composed of lishenmei ln5s03 and Cr micro low voltage MOS; The protocol adopts qc4 + Certification chip ip2726 of ICIC to control the fast charging of the two interfaces, with intelligent output and guaranteed compatibility.
