SCOPE

COPPER STRIP

Use a 0.1

µF @50V X7R ceramic capacitor (connected an inch away from the output

terminals of the UUT) and a 10

µF @ 25V tantalum capacitor (2 inches away from

the output terminals of the UUT). Scope measurement should be made using a BNC

socket, positioned 3 inches away from output terminals of the converter.

BATTERY

TO OSCILLOSCOPE

Measure input reflected-ripple current with a simulated source inductance (Ltest) of

12 uH. Capacitor Cs offsets possible battery impedance. Measure current as shown

above.
