(20 mA/div
Figure 14: Output voltage ripple at nominal input voltage and
rated load current (Io=33A)(50 mV/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 51mm to 76mm (2 inches to 3
inches) from the module.
