Figure 13: Test set-up diagram showing measurement points for Input Terminal
Ripple Current (Figure 14), Input Reflected Current (Figure 15) and Output
Voltage Ripple (Figure 16).
Figure 14: Input Terminal Ripple Current, ic, at full rated output current and
nominal input voltage with 5 µH source impedance and 47 µF electrolytic
capacitor (100 mA/div). See Figure 13.
Figure 15: Input reflected ripple current, is, through a 5 µH source inductor,
using a 47 µF electrolytic input capacitor (10 mA/div). See Figure 13.
Figure 16: Output voltage ripple at nominal input voltage and rated load current
(200 mV/div). Load capacitance: 1 µF ceramic capacitor and 330 µF elctrolytic
capacitor. Bandwidth: 20 MHz. See Figure 13.
Figure 17: Rise of output voltage after the removal of a short circuit across
the output terminals. Rshort = 5 mΩ. Ch1: (20 V/div). Ch2: Iout (50 A/div).
Bandwidth: 20 MHz.
