REFERENCE DESIGN
Transient Response and Output Ripple Voltage
The output ripple is about 15 mVPP at 20-A output. When the load changes from 4 A to 20 A, the overshooting
voltage is about 35 mV.
Figures 32 and 33 show the transient waveform with and without the transient comparator. Using the transient
comparator yields a settling time of 10-
s faster than without.
The output ripple is about 15 mVPP at 20-A output which is shown in Figure 32. When the load changes from
0 A to 13 A, the overshoot voltage is approximately 80 mV, and the undershoot is is approximately 60 mV as
shown in Figure 34. When the transient comparator is triggered, the powergood (PWRGD) signal goes low.
