Fig. 3.3V.11: Output voltage ripple (20 mV/div.) at full rated
load current into a resistive load with Co = 10 µF tantalum + 1
µF ceramic and Vin = 48 V. Time scale: 1 µs/div..
Fig. 3.3V.13: Input reflected-ripple current, i
measured at input terminals at full rated load current and Vin =
48 V. Refer to Fig. 3.3V.12 for test setup. Time scale: 1 µs/div.
Fig. 3.3V.15: Output voltage vs. load current showing current
limit point and converter shutdown point. Input voltage has
almost no effect on current limit characteristic.
