DC-DC powers the motor.
Figure 3 shows the waveform of the SW pin of the DC-DC when the motor is powered on but not rotating;
Figure 4 shows the waveform of the SW pin of the DC-DC at the moment when
The picture shows a push-pull emitter follower in the book "Transistor Circuit Design". A complementary pair of transistors is used, and the emitter current of Tr1 is about 1mA, so why is the current
