QM48T50012 DC-DC Converter Data Sheet
36-75 VDC Input; 1.2 VDC @ 50A Output
Fig. 32: Input reflected ripple current, i c (100 mA/div), meas-
ured at input terminals at full rated load current on both outputs
and Vin = 48 V. Refer to Fig. 31 for test setup. Time scale: 1
μ s/div.
Fig. 33: Input reflected ripple current, i s (10 mA/div), measured
through 10 μ H at the source at full rated load current on both
outputs and Vin = 48 V. Refer to Fig. 31 for test setup. Time
scale: 1 μ s/div.
