I'm going to use the MP2307DN to make a 2A, 5V circuit. I found an old schematic and it's a proven circuit! It works, but when I opened the "datasheet", I found the circuit diagram was like this.
Ther...
As shown in the picture, when I change the voltage, the current remains unchanged, but when I change the resistance of R2, the current changes. Why is that?...
