ELECTRICAL CHARACTERISTICS CURVES

current and nominal input voltage with 12µH source impedance and

33µF electrolytic capacitor (50mA/div, 2us/div)

inductor at nominal input voltage and rated load current (20

mA/div, 2us/div)

current (Io=3A) (50 mV/div, 5us/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
