Figure 8: 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 12: Output voltage ripple at nominal input voltage
(Vin=48V) and rated load current (Io=35A) (20mV/div,
2us/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
