Characteristic Curves
The following figures provide typical characteristics curves for the QRW040A0Y (VO = 1.8 V) module at room temperature (TA
= 25 °C)
Figure 19. Input Voltage and Current Characteristics.
Figure 20. Converter Efficiency vs. Output Current.
Figure 21. Output Ripple Voltage (IO = IO, max).
Tested with a 220µF aluminium and a 1.0µF ceramic capacitor
across the load.
Figure 22. Transient Response to Step Decrease in
Load from 50% to 25% of Full Load
(VI = 48 Vdc).
Figure 23. Transient Response to Step Increase in
Load from 50% to 75% of Full Load
(VI = 48 Vdc).
Tested with a 10µF aluminium and a 1.0µF tantalum capacitor
across the load.
