3×8 LED drive circuit diagram with overvoltage protection function

Resistors R1 and R2 ensure a constant output voltage that does not rise indefinitely by feeding back the output voltage to the error amplifier pin FB. The added circuit can protect the device from being damaged by excessive output voltage. The function of VD2 is to prevent Yang and Rcc from being connected in parallel when the LED module is not connected, and to prevent output overvoltage, because the resistance of R1 is much larger than the parallel value of R2 and Rcc.
