Characteristic Curves
The following figures provide typical characteristics curves for the QRW010A0B (VO = 12.0V) module at room temperature (TA
= 25 °C)
Figure 43. Input Voltage and Current Characteristics.
Figure 44. Converter Efficiency vs. Output Current.
Figure 45. Output Ripple Voltage (IO = IO, max).
Tested with a 220µF aluminium and a 1.0µF ceramic capacitor
across the load.
Figure 46. Transient Response to Step Decrease in
Load from 50% to 25% of Full Load
(VI = 48 Vdc).
Figure 47. 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.
