3.3 Load Transients

Figure 3-5 represents a load transient at 48VIN with a 12.5A to 37.5A load step, and then a 37.5A to 12.5A load dump. The load transient is totaling a 25% to 75% step at about an 4A/us slew rate and demonstrates an overshoot and undershoot of about 5% or less.

Figure 3-6 represents a load transient at 48VIN with a 25A to 50A load step, and then a 50A to 25A load dump. The load transient is totaling a 50% to 100% step at about an 4A/us slew rate and demonstrates an overshoot and undershoot of about 5% or less.
