NE555 Duty Cycle

  One. Function description:
1. After power on, the output terminal outputs a square wave signal, the amplitude is approximately equal to the power supply voltage.
2. The output frequency is not adjustable, and the output frequency is basically stable during the process of adjusting the duty cycle.
3. Frequency (measured under 5V power supply, the frequency allows 10% deviation): default 1kHz
4. The duty cycle is adjusted by the built-in multi-turn potentiometer, and the adjustment range is 1% to 99% (3%-97% for 10kHz modules).

Two. power supply:
The power supply voltage is DC 5V-15V, the no-load working current is about 2.2mA at 5V, and the no-load working current is about 6.0mA at 12V.

Three. Output drive current:
200mA MAX.
Four. use:
Used as a signal source in the circuit.
Five: How to use:
1. It can work when connected to the power supply.
2. When in use, a 0.1uf power supply filter capacitor can be connected to the power supply terminal to make the work stable.
3. Adjust the potentiometer clockwise to increase the duty cycle, and adjust the potentiometer counterclockwise to decrease the duty cycle.
six. size:
Excluding the pin size 13mm×11mm×8mm. The pin spacing is 2.54mm.
