QD48S018033 DC-DC Converter Data Sheet
36-75 VDC Input; 1.8 – 3.3 VDC @ 15A Output
Fig. 32: Load current Iout1 into a 10 m ? short circuit on Vout1
during restart, with Vout2 open (no load), at Vin = 48 V. Ch2 =
Iout1 (20 A/div, 20 ms/div). ChB = Iout1 (20 A/div, 1 ms/div) is
an expansion of the on-time portion of Iout1.
Fig. 33: Load current Iout2 into a 10 m ? short circuit on Vout2
during restart, with Vout1 open (no load), at Vin = 48 V. Ch2 =
Iout2 (20 A/div, 20 ms/div). ChB = Iout2 (20 A/div, 1 ms/div) is
an expansion of the on-time portion of Iout2.

Fig. 34: Output voltage ripple at full rated load current into a
resistive load on both outputs with Co = 1uF (ceramic) and Vin
= 48 V. Ch2 = Vout2, Ch1 = Vout1 (both 20 mV/div). Time
scale: 1 μ s/div.
