9.3.5 Drive Strength Adjustment

To allow for an adjustable slew rate to control stability and ringing in the circuit, as well as an adjustment to pass electro-magnetic compliance (EMC) standards, LMG341xR070 allows the user to adjust its drive strength. A resistor is connected the RDRV pin and ground. The value of the resistor determines the slew rate of the device during turn-on between 30V/ns and 100V/ns; see Figure 2 for the relationship between RDRV and the drain slew rate. The propagation delays vary with RDRV; consult Figure 1 for more details. The turn-off slew rate is dependent on the load current; therefore, it is not controlled.
