Resistance and capacitor selection, how to determine the configuration parameters, thank you!

Hello,

Bus capacitors, large capacitors, are voltage stabilizing capacitors, which need to be determined according to your actual load and voltage ripple; 100nF small capacitors are used to rate high frequencies.

As you can see, there is no gate resistor here, so the MOS turn-on speed is limited by increasing the capacitance, while the BDRV drive supports adjustment of the driving current. Here, C24 needs to be determined based on actual testing conditions, if you look at the actual development board without welding.

The RC here is to filter the high frequency at the moment of opening, and it also requires actual testing to determine. Also, there is no welding on the development board.
