Figure 14: Output voltage ripple at nominal input voltage (Vin=48V) and rated load current (Io=30A) (20 mV/div). Load capacitance: 1µF ceramic capacitor and 10µF 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 and 76 mm (2 inches and 3 inches) from the module.
