Characteristic Curves
The following figures provide typical characteristics curves for the QRW040A0S1R0 (VO = 1.0 V) module at room temperature
(TA = 25 °C).The figures are identical for both on/off configurations.
Figure 1. Input Voltage and Current Characteristics.
Figure 2. Converter Efficiency vs. Output Current.
Figure 3. Output Ripple Voltage (IO = IO, max).
Tested with a 220µF aluminium and a 1.0µF ceramic
capacitor across the load.
Figure 4. Transient Response to Step decrease in
Load from 50% to 25% of Full Load (VI = 48
Vdc).
Figure 5. Transient Response to Step Increase in Load
from 50% to 75% of Full Load (VI = 48 Vdc).
Figure 6. Start-up from Remote On/Off (IO = IO, max).
