ELECTRICAL CHARACTERISTIC CURVES

Figure 9: Input Terminal Ripple Current, ic, at full rated output

current and nominal input voltage with 12µH source impedance

and 100µF electrolytic capacitor (200 mA/div).

Figure 10: Input reflected ripple current, is, through a 12µH

source inductor at nominal input voltage and rated load current

(5 mA/div).

LOAD

Figure 11: Output voltage noise and ripple measurement test

setup.

Figure 12: Output voltage ripple at nominal input voltage and

rated load current (50 mV/div). Load capacitance: 1µF ceramic

capacitor and 10µF tantalum 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.
