Recently, the charging head network got a very small car charge from PISEN Pinsheng, but the product is equipped with a 1A1C dual output interface, and supports a maximum of 18W and 20W fast charging, respectively, and compatible fast charging protocols are also rich. The charging head network understands that it is such a car charger, and its internal use only uses an English core IP6566 to achieve the above rich functions. Let's take a detailed breakdown of the car charge and see how the product is designed today.
First, Pinsheng 20W car charging appearance
The front of the box is printed with information such as PISEN Pinsheng, product appearance, name and selling points.
Product parameters and business information are printed on the back.
The package contains a car charge and warranty card.
The car charge adopts a black shell made of PC material, the surface is mainly frosted, and the two ends are also designed with bright ring decoration.
The fuselage is printed with the PISEN brand logo.
The other side is printed with car charging parameters
Model: LP-CC22
Input: DC 12-24V
output:
USB-C：5V3A、9V2.22A、12V1.67A
USB-A：5V3A、9V2A、12V1.5A
A+C：5V3A
Maximum output: 20W
Manufacturer: Shenzhen Travel Technology Co., Ltd
The top surface is equipped with dual output interfaces of 1A1C, all of which are in classic yellow color.
The intuitive feeling of the car charge in the hand is very small.
The weight is only 15g.
The built-in LED that is plugged in to power on is blue.
The USB-C port was measured using the Chargelab POWER-Z KT002 to support Apple 2.4A, Samsung 5V2A, DCP protocol, and QC2.0/3.0, FCP, SCP, PD3.0, ppS fast charging protocol.
And it has three fixed voltage gears of 5V3A, 9V2.22A, 12V1.67A, and a set of PPS voltage gears of 3.3-11V2A.
In addition, the USB-A port supports QC2.0/3.0, FCP, and SCP fast charging protocols.
Second, Pinsheng 20W car charge disassembly
Remove the top shell and remove the car charge.
The small plate is covered with a thermal pad on one side.
Below is the IP6566 IC of Injeweek, and the thermal pad helps the chip dissipate heat.
Filter capacitors and buck inductors are provided on the other side of the board.

The INJI core IP6566 is used to realize input step-down and control the 1A1C dual-port output. This is a step-down converter with integrated synchronous switching, support for multiple output fast charging protocols, and dual-port output SOC IC supporting Type-C output and USB PD2.0/PD3.0 (PPS) protocols, providing a complete solution for car chargers, fast charging adapters, and smart row plugs.
IP6566 supports dual C, 1A1C or dual A port output, integrated dual port automatic plug detection function, use any one port alone can support fast charge output, when the dual port is used at the same time, the dual port output 5V, the total power 5V3.4A.
Ip6566 built-in power MOS, support 8.2-32V wide range input and 3-12V output, can provide a maximum output power of 20W, can automatically adjust the output voltage and current according to the identified fast charging protocol. IP6566 output 5V/3A, board-terminated
The change efficiency is as high as 93.8%.
The IP6566 features a soft-start function that prevents inrush current at startup from affecting the stability of the input supply. In addition, it also has a variety of protection functions: input overvoltage, undervoltage protection, output overcurrent, overvoltage, undervoltage, short circuit protection and other functions. Space-saving available in a 4*4mm QFN28 package.
Charging head network learned that the fast charging chip of Yingjixin can be widely used in chargers, mobile power, wireless charging, car charging, energy storage power supply and other fields, and has been adopted by dozens of products of well-known brands such as Xiaomi, Huawei, Samsung, etc., and the product quality has been unanimously recognized by customers.

Charging head net disassembly summary
Thanks to the use of Yingjixin IP6566, Pinsheng car charging is compatible with QC2.0/3.0, FCP, SCP, PD3.0, PPS fast charging protocol, and has a 3.3-11V2A PPS voltage gear, has good compatibility, supports the hot 20W fast charging on the market, and meets the needs of iPhone 12/13 mobile phone fast charging.
Yingjixin IP6566 integration is very high, just as Pinsheng this car charger shows, based on the chip can be designed very small and can be configured with dual C port, 1A1C interface or double A port fast charging products, and can greatly reduce the design difficulty and cost, to achieve rapid product listing, and both exquisite appearance and practicality.
