2. Connect to the emitter of the internal drive tube. Connect it to the drive current sense pin RE at low power. If it is not connected to the RE pin at high power.
3. Output rising voltage inductor;
4. Output rising voltage power switch tube;
5. Output rising voltage power switch tube working current detecting resistor;
6. Output rising voltage diode;
7. RC frequency compensation circuit for stabilizing the operation of the circuit;
8. Output sampling resistor to stabilize the output voltage to the output voltage determined by the internal reference stable voltage;
9. Output filter capacitor to stabilize the output voltage and reduce the ripple voltage applied to the load.
