4.5 Load Transient

Figure 4-7 and Figure 4-8 show the load transient waveforms for each channel. When load is stepped from 0 A to 5 A, the undershoot voltage is less than 60 mV and the settling time is less than 30 μs. When load is stepped down from 5 A to 0 A, the overshoot voltage is less than 50 mV and the settling time is less than 50 μs.
