The range of input voltages for your Pulse Width Modulation (PWM) controller will depend on several factors, including the components you are using, especially the LM555 timer IC and the MOSFET SIR680ADP-T1-RE3.
Here are the primary considerations:
  1. LM555 Timer IC (LM555CM):
    • The standard operating voltage range for the LM555CM is 4.5V to 16V.
  2. MOSFET (SIR680ADP-T1-RE3):
    • The SIR680ADP-T1-RE3 can withstand a maximum drain-source voltage ($V_{DS}$) of 100V, with a gate threshold voltage ($V_{GS}$) typically between 2V to 4V.
  3. Input Voltage Considerations:
    • Ensure your power supply voltage (VIN) is within the safe operating range of the LM555 timer (4.5V to 16V).
    • Ensure that any voltage applied to the MOSFET gate is within its $V_{GS}$ rating and that the drain-source voltage does not exceed the maximum $V_{DS}$.
Assumptions
  • You are using the LM555 as a PWM controller and the MOSFET to drive the load.
  • The input power voltage (VIN) should be 4.5V to 16V based on the LM555 timer IC requirements.
Therefore, the safe range of input voltages (VIN) for your PWM controller is 4.5V to 16V.
If you have any specific requirements or questions, let me know!
