Figure 12: Output voltage ripple at 36V input voltage and rated

load current (50 mV/div). Load capacitance: 1µF ceramic

capacitor and 10µF tantalum capacitor. Bandwidth: 25 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.

Figure 13: Output voltage ripple at 48V input voltage and

rated load current (50 mV/div). Load capacitance: 1µF

ceramic capacitor and 10µF tantalum capacitor. Bandwidth:

25 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.
