我们可以通过对采样电阻的阻值进行一定的调整等操作，来改变设计电路对最高

We can change the limit of the maximum output current of the design circuit by adjusting the resistance of the sampling resistor to a certain extent. It is generally considered that the feedback part of the current limiting circuit, that is, the voltage value on the No. 3 pin of the chip, has the interference of sharp pulses. This interference is caused by the inter-turn capacitance of the transformer and the recovery time of the output rectifier tube. We will build a spike filter circuit to eliminate such interference. Prevent the occurrence of false turn-off and ensure the stability and accuracy of the circuit operation. The circuit structure is shown in the figure:

It is generally considered that the feedback part of the current limiting circuit, that is, the voltage value on pin 3 of the chip, has the interference of sharp wave pulse. This interference is caused by the inter turn capacitance of the transformer and the recovery time of the rectifier at the output end.
