The picture is a curve chart of MMBT3904. There are 4 questions as follows:
1. What does the "Base-Emitter Saturation Voltage" in the figure mean? How is it different from the base-emitter voltage dro
In a single-ended flyback switching power supply, the primary input of the transformer is a DC voltage, and the secondary output is also a DC voltage.
How is the input DC converted into AC through the
Figure 1 is the circuit in use, but because the external input terminal is in high impedance state when there is no input, it is sometimes unstable. I want to connect a 50K resistor directly between p
