Input Reflected Ripple Current, is, at full rated output
current and nominal input voltage with 12 µ H source impedance
and 100 µ F electrolytic capacitor (2 mA/div).
Figure 10: Output voltage noise and ripple measurement test
setup. Scope measurement should be made using a BNC
cable (length shorter than 20 inches). Position the load
between 51 mm to 76 mm (2 inches to 3 inches) from the
module.
