Disassembling report: Yingcai Star 30W dual USB car charger
INTROSAN Talent Star was established in 2011. It focuses on original design, research and development, production, and sales of auto peripheral products, and in 2018, it became a supplier of the German Bo Shi (B0SCH). Recently, Yingcai has launched a CAR Charger C2 -certified car charger CAR Charger C2, a Qualcomm QC3.0 certification. This car charging adopts a dual USB-A interface design with 18W+12W independent output power configuration. In addition to supporting the QC3.0 protocol, the fast charging interface also supports FCP, AFC, Apple 2.4A and other protocols. The compatibility is very compatible good. At present, the charging head network has disassembled this product, and the detailed disassembly content is below.
1. Introsan Yingci Star dual USB car charger appearance
This car charger is packaged in a corrugated paper aircraft box, which looks very simple. The front seal is labeled with a product label. Product name: Car Charger C2 metal intelligent fast charge. Four major selling points of the product: 5.4A output, QC3.0 fast charge, voltage monitoring, metal material.
There is a brand logo on the top of the packaging box.
The back is detailed parameter information, and the manufacturer is Guangzhou Dali Electronic Technology Co., Ltd.
The packaging box is protected by transparent plastic lining. The packaging is lightweight and the shock absorption effect is good, which is convenient for e -commerce channel sales.
This car charging uses a all -metal body with a frosted and anode oxidation technology on the surface. It feels delicate and the fuselage laser “Introsan” brand logo. The positive pole uses a cylindrical thimble, the negative extremely lumbar spherical shot, the car charges the tail and the head is excessive, and it looks very natural.
On the other side, there is a conspicuous QC3.0 certification sign, which also shows that this product has passed the Qualcomm QC3.0 certification. The nominal output parameter shows that OUTPUT1: 5V/2.4A, OUTPUT2: 3.6-6.5V/3A (MAX), 6.5-9V/2A, 9-12V/1.5A (MAX).
The output end has two USB-A interfaces, supports QC3.0 and 2.4A outputs, and is distinguished with two types of glue cores: orange and black. The edge of the output end adopts a high -gloss chamfer process, forming a bright surface ring for decoration.
The two USB-A output interfaces are directly a LED digital display, with hidden design, and it is not easy to find without connecting the power.
It is also because of the design of several display screens, so the end surface of this car charging is slightly larger than a one -dollar coin.
In the case of connecting the power, the built -in LED screen will light up, and the current voltage value will be displayed when the air load is empty.
Introsan’s car charging supports both 12V voltage input and 24V voltage output, covering the voltage of most models on the market.
The net weight of the car is about 32g.
Use ChargerLab Power-Z KT001 to detect the output protocol of the OUTPUT1 port to show two charging protocols that support Apple 2.4A and USB DCP, and do not support other fast charging.
Continue to detect the output protocol of the OUTPUT2 port, showing that in addition to supporting Apple 2.4A and USB DCP charging protocols, it also supports QC2.0, QC3.0, AFC, FCP and other fast charging protocols.
Second, Introsan Yingcai Double USB car charger disassembling
From the output end panel, open the charging shell, and the end surface cover is fitted with double -sided glue. A LED digital tube can be seen between the two USB output interfaces.
Continue to remove the plastic band between the interfaces.
The internal PCBA and the shell are treated with glue. On the one hand, it plays a fixed effect and increases reliability. On the other hand, it can play a certain thermal conductivity.
Take out the internal PCBA and consists of two spans PCB boards. Among them, the inductance, capacitance and other plug -in components on the PCB board are also used for adhesive injection. The negative bullets are directly welded on the PCB board. Processing, increasing the requirements of ditage, and meeting the requirements of large current output.
The back of the power board is the main control chip of the two cars. In addition, no other components are seen, and the periphery is relatively simple.
One of the chips is an IP6525T from the British core. This is a lower -voltage converter that integrates synchronous switches and supports 4 output fast charging protocols. Its built -in power MOS, the antihypertensive conversion efficiency is as high as 98%, the input voltage range range It is 9.6V to 32V, and the output voltage range is 3V to 12V. The maximum output power can be provided by 18W. The output voltage and current can be automatically adjusted according to the recognized fast charge protocol. The typical output voltage and current are 5V/3.4A, 9V/// 2.0A, 12V/1.5A, provide complete solutions for vehicle chargers, fast -filled adapters, and smart exclusive insertions.
British IP6525T specifications.
Another chip also comes from the British core, the model IP6523s. It is an integrated simultaneous switching transition converter, supporting DCP (BC1.2, Apple, Samsung) protocol. Its built -in power MOS has a lower -voltage conversion efficiency of more than 96%. The input voltage range is 9.6V to 32V. The voltage is 5V, which can provide a maximum output current of 3.4A, providing a complete solution for vehicle chargers, fast -filled adapters, and smart exclusive insertions.
British Xinxin IP6523S detailed specifications.
Enter the filter electrolytic capacitance with 35V 220 μF.
Output filter electrolytic capacitance with a specification of 16V 220 μF.
There is an output filter capacitor under the LED display with a specification of 16V 220 μF.
Anti -voltage inductance, this car uses a total of two inductors, controlled by IP6523S and IP6525T, respectively to achieve synchronous antihypertensive functions.
There is also a single -chip microcomputer on the back of the output interface PCB board for the driver of the LED display.
All Introsan car charges have been disassembled.
Summary of charging head network disassembly
Introsan’s CAR Charger C2 car charger uses a all -metal body with a texture and holds in the hand. Equipped with two USB-A output interfaces, which can meet the power needs of main driving and co-driving drivers in the car, and the car charging is two independent output. Even if the two devices are charged at the same time Said, the user’s experience is very good.
The disassembly of the charging head network found that the product inside this product uses the British core IP6525T and IP6523S main control chip, which realize the 18W fast charging output and 12W output, respectively. There are few peripheral components. The simple PCB board is simple, which is conducive to accelerating the development and listing of products.
