ELECTRICAL CHARACTERISTICS CURVES
Figure 7:
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 8:
Input Terminal Ripple Current, ic, at full rated output
current and nominal input voltage with 12H source impedance
and 33F electrolytic capacitor (50 mA/div).
Figure 9:
Output voltage noise and ripple measurement test
setup.
Figure 10:
Output voltage ripple at nominal input voltage and
rated load current (20mV/div). Load capacitance: 2200uF*2
electrical capacitor, 0.47F ceramic capacitor and 10F
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.
