Fig. 22: Output voltage ripple (20 mV/div.) at full rated load
current into a resistive load with Co = 10 µF tantalum + 1uF ce-
ramic and Vin = 24 V. Time scale: 1 µs/div.
Fig. 23: Test setup for measuring input reflected ripple cur-
rents, i_c and i_s.
Fig. 24: Input reflected ripple current, i_c (100 mA/div), meas-
ured at input terminals at full rated load current and Vin = 24 V.
Refer to Fig. 23 for test setup. Time scale: 1 µs/div.
Fig. 25: Input reflected ripple current, i_s (10 mA/div), measured
through 10 µH at the source at full rated load current and Vin =
24 V. Refer to Fig. 23 for test setup. Time scale: 1µs/div.
