QD48S018033 DC-DC Converter Data Sheet
36-75 VDC Input; 1.8 – 3.3 VDC @ 15A Output
Fig. 28: Output voltage response to both Iout1 and Iout2 (out
of phase) load current step-change of 3.75 A (50%-75%-50%)
at Vin = 48 V. Ch1 = Vout1 (50 mV/div), Ch2 = Vout2 (50
mV/div), Ch3 = Iout1 (10 A/div.), Ch4 = Iout2 (10 A/div.). Cur-
rent slew rate: 0.1 A/ μ s, Co = 10 μ F tantalum + 1 μ F ceramic.
Time scale: 1 ms/div.

Fig. 29: Output voltage response to both Iout1 and Iout2 (out
of phase) load current step-change of 3.75 A (50%-75%-50%)
at Vin = 48 V. Ch1 = Vout1 (100 mV/div), Ch2 = Vout2 (100
mV/div), Ch3 = Iout1 (10 A/div.), Ch4 = Iout2 (10 A/div.). Cur-
rent slew rate: 5 A/ μ s, Co = 300 μ F tantalum + 1 μ F ceramic.
Time scale: 1 ms/div.
Note: The only cross-talk during transient is due to the com-
mon RETURN pin for both outputs.

Iout [Adc]
Fig. 30: Output voltage Vout1 vs. load current Iout1 showing
current limit point and converter shutdown point. When Vout1
is in current limit, Vout2 is not affected until Vout 1 reaches the
shut-down threshold of 1 V. Input voltage has almost no effect
on Vout1 current limit characteristic.
Iout [Adc]
Fig. 31: Output voltage Vout2 vs. load current Iout2 showing
current limit point and converter shutdown point. When Vout2
is in current limit, Vout1 will follow with less than 0.6 V differ-
ence until shut-down threshold of 1 V. Input voltage has almost
no effect on Vout2 current limit characteristic.
