Figure 9: Input Reflected Ripple Current, is, at full rated output current and nominal input voltage with 12µH source impedance and 33µF electrolytic capacitor (2 mA/div).
Figure 11: Output voltage ripple at nominal input voltage and
rated load current (20 mV/div). Load capacitance: 1µF ceramic
capacitor and 10µF tantalum capacitor. Bandwidth: 20 MHz.
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.
