dob Posted April 8, 2021 Share Posted April 8, 2021 This is a PWM signal generating circuit based on LM393. When I was running this LM393 circuit, I found that this circuit only consumes about 10 milliwatts of power at a voltage of 5V. Not only that, this circuit can work normally at 3.3V, 12V and 18V. But later I found that this circuit cannot be used in switching power supplies. It is missing something: dead time. So I would like to ask you how to make some changes to this circuit?
