- This is a PWM signal generating circuit based on LM393 but cannot be used in switching power supplies. How can I do?
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?
