Fig. 12V.13: Output voltage ripple (50 mV/div.) at full rated
load current into a resistive load with Co = 10 μF tantalum +
1uF ceramic and Vin = 24 V. Time scale: 1 μs/div.
Fig. 12V.15: Input reflected ripple current, i
measured at input terminals at full rated load current and Vin =
24V. Refer to Fig. 12V.14 for test setup. Time scale: 1 μs/div.
