thank you very much for the response. can you send visual aid to help me understand more about it and then ill try if i can make it to electronic workbench.Welcome, Well if you're really new, the 555 would be set up to make the on/off pulse signal going to the gate of the mosfet. Typically for lowside nmos, I see a very small resistor, like 2.2 to 22 ohms resistor, from the pulse width modulation output, to the gate, and to a 10k ohm resistor to GND. As for a good 555 circuit for PWM, I'm not sure myself, I used 1 lately, but didn't take the time to understand how it worked.
555 can gen pwm but you would need a hell lot of other things.hey. can somebody help with my project, i need to make a buck-boost converter using electronic workbench, i dont know how to power the mosfet using 555 or any components. thanks.
