SY8368-CC module

SY8368-CC DC-DC step-down constant current power supply module is specially designed for supercapacitor constant current charging. After the module is powered off, it can prevent capacitor reverse leakage protection.
 
Constant current principle: the output voltage and load internal resistance are constant, and the output current is constant. The output shunt resistor voltage is collected by the op amp to obtain the current and set the current voltage. The control chip FB voltage is used to control the output voltage to achieve output constant current.
 
TYPE-C fast charging can lure up to 100W (20V5A)
Recommendation: VBUS <= 20V / VOUT < VBUS - 2V
Input voltage range: 5V~21V
Output voltage adjustable range: 0.6V~20V
Output constant current adjustable range: 0A~12A
Input power = Output power + Various losses
 
Note:
For long-term use of high current, it is recommended to force heat dissipation.
The potentiometer has limited accuracy Unable to perform high-precision adjustment.
The chip has its own protection function. In some cases, it may be started first. The constant current cannot be
reproduced normally. The component parameters are subject to the schematic diagram. The BOM table automatically generated by Jiali Chuang EDA may have problems.
