Figure 8 Output voltage response to step-change in load current 50%-75%-50% of Imax dI/dt = 0.1A/µs.Vin=48V. Load cap 10µF, tantalum capacitor and 1µF ceramic capacitor. Top trace Vout 100mV/div, Bottom trace Iout 10A/div. Scope measurement should be made using a BNC cable length shorter than 20 inch. Position the load between 51 mm and 76 mm 2 inches and 3 inches from the module
Figure 13 Output voltage noise and ripple measurement test setup
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
