SY8368-CP module

SY8368-CCP DC-DC step-down constant current and constant power power supply module is specially designed for supercapacitor constant current and constant power charging. After the module is powered off, it prevents capacitor reverse inflow and leakage protection.
Constant power principle: When the input voltage and current are constant, the output power will be constant through operation. Collect the input shunt resistor voltage to get the current and compare the set current and voltage to control the chip FB voltage to control the output voltage to achieve constant output power.
 
TYPE-C fast charging can deceive a maximum of 100W (20V5A)
. Recommendation: VBUS <= 20V / VOUT < VBUS - 2V
input voltage range: 5V~21V
Output voltage adjustable range: 0.6V~20V
Input constant current adjustable range: 0A~6.2A When the input voltage and current are constant, the output power is constant
Input power = Output power + Various losses
 
Note:
Long time It is recommended to use high current and force the heat dissipation.
The potentiometer has limited accuracy and cannot perform high-precision adjustment.
The chip has a built-in protection function. In some cases, it may be started preferentially. The constant current and constant power cannot be reproduced normally.
The component parameters are subject to the schematic diagram. The BOM automatically generated by Jialichuang EDA. There may be a problem with the table.
