Figure 12. Maximum output voltage ripple in burst mode at 50 % duty cycle
The maximum output voltage ripple is 114 mV (peak-to-peak).
5.7 Dynamic load response
The dynamic load response test shows the result of constant load steps across the
output. Output current of the converter is changed in steps of between 0 A and 20 A at a
repetition frequency of 1 Hz, 10 Hz, 100 Hz, and 1000 Hz.
