ELECTRICAL CHARACTERISTICS CURVES

voltage and rated load current with 12µH source impedance

and 150µF electrolytic capacitor (200 mA/div).

inductor at nominal input voltage and rated load current

(50 mA/div).

Figure 11: Output voltage noise and ripple measurement

test setup.

Figure 12: Output voltage ripple at nominal input voltage and

rated load current (20 mV/div). Load capacitance: 100µF ceramic

capacitor and 220µF electrolytic capacitor. Bandwidth: 20 MHz.

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.
