SOP-8Summary:
The CX8820C has the function of automatically identifying the VIN input voltage and adjusting the output power based on the input voltage. Built in power MOS, with an input working voltage of up to 31V and an output voltage range of 3.3V to 21V, it can provide a maximum output power of 45W and automatically adjust the output voltage and current according to the recognized fast charging protocol.
The output of CX8820C has CV/CC characteristics. When the output current is less than the set value, it outputs in CV mode and the output voltage is constant; When the output current is greater than the set value, output CC mode and output voltage decrease.
The output voltage of CX8820C is equipped with wired compensation function. When the output current increases, it will correspondingly increase the output voltage to compensate for the voltage drop caused by the impedance of the connecting line.
CX8820C supports secondary burning and can be upgraded online.
CX8820C has multiple protection functions, including input overvoltage and undervoltage protection output short-circuit and overcurrent protection, and over temperature protection.
We can provide a complete solution for power supply equipment such as car chargers, various fast charging adapters, and intelligent battery plugs.
