Hi everyone, how are you, hope you are all doing well. I would like to use the IR2104 ic to drive two mosfets in a buck convert with a frequency of around 31khz in this config down below but wonder how to do this in flowcode with a pic. Please help with details of how to go about this.

Hello Derrihj
This is not the answer for your question, but a suggestion from my own experience.
I tried to use Arduino to send PWM signal to Nano, however later I found out the existence of the dedicated PWM controllers (SG3526, UC3842, etc) with build-in protection functions (and a better feedback).
Finally I have changed the schematic by leaving to Arduino the main control of the charging process.
There are two types of charging control -> by voltage and by current.
The mosfet driver I used -> TC4420.

I really want to know how to drive this with a PIC.
