I'm making a buck converter with the following characteristics:
Input voltage: 24V
Output voltage: 5V-20V
Max current: 5A
*Constrains: The transistor driver must be an IR2110
I have the following doubts:
Is it necessary connect and to control the high side and low side transistors even when I only need to use the high side one?
Can I check the output signal of the IR2110 before connect the transistor?
How is selected the value of the resistance RG?
Vs and Vcc aren't connected, that was and error in the image.
I have the above circuit but with the transistor disconnected, and I'm testing the signal between pins 7 and 5 with a led, it does not turn on, but when I connect the led between pin 7 and ground it does turn on. What could be the issue?
I've simulated the circuit, but the result is not as expected.
The imput voltage is 20V and the duty cicle 50% so the output should be 20V, but instead I get a transient signal then just a 0V output.
For the IR2110 the green signal is the input, at pin 10, the blue one is the output at pin 7, and the red signal is the voltage at the load.
