Main control chip: ip6505

IP6505 is a buck converter with integrated synchronous switch, supports 11 output fast charging protocols , and provides a complete solution for car chargers , fast charging adapters, and smart power strips . IP6505 has a built-in power MOS . The input voltage range is 4.5 V to 32 V , and the output voltage range is 3V to 12 V. It can provide a maximum output power of 24 W. It can automatically adjust the output voltage and current according to the recognized fast charging protocol . Typical output voltages and currents are: 4 V@ 3.6 A , 5V@3.4 A , 7V@ 3 A , 9V @ 2.5 A , 12V @ 2 A. The buck conversion efficiency of IP6505 is as high as 97 % . The output of IP6505 has CV/CC characteristics. When the output current is less than the set value, it outputs CV mode and the output voltage is constant; when the output current is greater than the set value, it outputs CC mode and the output voltage decreases . The output voltage of IP6505 has a line compensation function. When the output current increases the output voltage will increase accordingly to compensate for the voltage drop caused by the impedance of the connecting line. IP6505 has a variety of protection functions , including input overvoltage and undervoltage protection, output overcurrent, overvoltage, undervoltage, short circuit protection, etc.

Jiali Chuangzi is really good

Because I don’t have a USB power meter, I can’t measure power, ripple, etc. (If you have money, you can buy a yzx 1280e)
