SY8368-CCP 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 current principle: The output voltage and load internal resistance are constant and the output current is The constant current is obtained by collecting the voltage of the output shunt resistor through the op amp and the set current voltage is compared with the voltage of the control chip FB to control the output voltage to realize the output constant current and
constant power. Principle: When the input voltage and current are constant, the output power is constant and obtained by collecting the voltage of the input shunt resistor by the op amp. The current and the set current voltage are compared with the FB voltage of the control chip to control the output voltage to achieve constant output power.
 
TYPE-C fast charging can deceive 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~10A
input constant current adjustable range: 0A~10A
input power = output power + various losses
 
Note:
forced heat dissipation is recommended for long-term use of high current
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 and cannot be used for normal constant current and
constant power. The component parameters are subject to the schematic diagram. The BOM table automatically generated by Jialichuang EDA may have problems.
