Figure 12: Input reflected ripple current, i_s, through a 12µH
source inductor at nominal input voltage and rated load current
(20 mA/div, 2us/div).
Figure 13: Output voltage noise and ripple measurement test
setup.
Figure 14: Output voltage ripple at nominal input voltage and
rated load current (50 mV/div, 2us/div). Load capacitance: 1µF
ceramic capacitor and 10µF tantalum capacitor. Bandwidth: 20
MHz. Scope measurements 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.
