Key Design Notes
The constant voltage (CV) mode control is implemented with resistors R8, R9, R10 and R11, shunt regulator U2, feedback
capacitor C9 and opto-coupler U3.
The constant current (CC) mode control is designed with resistors R8, R9, R15, R16, R17 and R19, NPN transistor Q1 and
NTC TH1. When the voltage across current sensing resistors R15,R16 and R17 is 0.7V, the NPN transistor turns on and the
current through the opto coupler LED increases. This reduces the feedback voltage and duty ratio. Therefore, the output
voltage decreases and the output current is regulated.
The NTC(negative thermal coefficient) resistor is used to compensate the temperature characteristics of the transistor Q1.
The zener diodes (ZD1, ZD2) are used to bypass the ESD or surge.
