Hi Jaeho,

I do not understand the question. The VdsQx = IQx*RDSonQx when the FETs are on (only 2 switching alternatively, Q1 or Q4 on full and Q2 or Q3 off). The Rdson values from the datasheet are below:

Jeff

Hi Jaeho,

If you want the max VDS rating of the FETs, you can use the datasheet abs max rating for SWx from the datasheet:
