Hey,
Im designing a step-down dc-dc converter. The input voltage is 7V and I want an output voltage of 2V. The control is done through PWM with an IC 555. The switching frequency is 300kHz.
I have tried to make it work, but it doesnt. I would like, you help me checking it to find any error. Please let me know what is happening with this circuit. I have attached the circuit design.
Thank you very much for your help.
