Fig. 20: Output voltage response to load current step-change
(5 A – 10 A – 5 A) at Vin = 48 V. Top trace: output voltage (100
mV/div). Bottom trace: load current (5 A/div.). Current slew
rate: 0.1 A/μs. Co = 1 μF ceramic. Time scale: 0.2 ms/div.
Fig. 18: Turn-on transient at full rated load current (resistive)
with no output capacitor at Vin = 48 V, triggered via ON/OFF
pin. Top trace: ON/OFF signal (5 V/div.). Bottom trace: output
voltage (2 V/div.) Time scale: 1 ms/div.
