I have a problem in IR2110 gate driver. I have given PWM at Hin(in phase) and Lin(out phase). The IC is working on the high side(Pin no1) but it is not working on the low side of the IC(Pin no 7). I have tried all the configurations but it is still not working. Please suggest me any remedy to my problem..

Re: full bridge converter eith mosfet and IR2110 gate driver

Dear pinki verma
Hi
Can you attach the schematic that you follow it ? By the way : did you try it in practice or perhaps you used a simulator ?

Is COM (pin 2) attached to the negative rail of the H bridge? Other than that your schematic looks fine.
