Note: 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.

Note: Use a 0.1 uF ceramic capacitor and a 10 uF tantalum capacitor. Scope measurement should be made
using a BNC socket. Position the load between 51 mm and 76 mm (2 in. and 3 in.) from module.
