hi expert
Currently, there are two types of silk-screen printing for the materials, as shown in the picture. Are there any functional differences between these two types of materials based on the silk-screen printing? Could you please explain the meaning of the silk-screen printing?
Power on the oscilloscope to test the two materials. There are still some slight differences in the waveforms. Please refer to the corresponding waveform diagrams. Currently, there is an abnormality when the silk-screen SAK is used on the board. Replacing it with the product 4CM has restored normal operation. We also kindly request you to confirm the cause of this problem.
It is used for current limiting. When the reverse terminal signal exceeds 5 * (5.1 / (5.1 + 1)), the output will be cut off. The new material starts to perform chopping at this position.The circuit diagram is as follows
