Figure 14: Output voltage ripple at nominal input voltage
(Vin=48V) and rated load current (Io=20A) (20 mV/div). Load
capacitance: 1µF ceramic capacitor and 10µF tantalum
capacitor. Bandwidth: 20 MHz. (See Figure 12) Scope
measurement should be made using a BNC
cable (length
shorter than 20 inches). Position the load between 51 mm and
76 mm (2 inches and 3 inches) from the module.
