The slew rate, measured in volts per nanosecond, is measured on the turn-on edge of the LMG341xR070. The slew rate is considered over the VDS fall time, where the drain falls from 80 percent to 20 percent of the bus voltage. The drain slew rate is thus given by 60 percent of the bus voltage divided by the VDS fall time. This drain slew rate is dependent on the RDRV value and is only slightly affected by drain current. Please refer to Figure 2 for the RDRV that is matched with the needed slew rate.
