ELECTRICAL CHARACTERISTICS CURVES

Figure 9: Test set-up diagram showing measurement points for Input Terminal Ripple Current and Input Reflected Ripple Current.

Note: Measured input reflected-ripple current with a simulated source Inductance (LTEST) of 12 μH. Capacitor Cs offset possible battery impedance. Measure current as shown above.

Figure 10: Input reflected ripple current, ic through a 12µH source inductor at nominal input voltage and rated load current (20 mA/div).
