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 10 µH source impedance and 47 µF ceramic
capacitor (50 mA/div). See Figure 13.
Figure 15: Input reflected ripple current, is, through a 10 µH source inductor,
using a 47 µF ceramic input capacitor (10 mA/div). See Figure 13.
Figure 16: Output voltage ripple at nominal input voltage and rated load current
(50 mV/div). Load capacitance: 1 µF ceramic capacitor and 15 µF tantalum
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: Vout (5 V/div). Ch 2: Iout (50 A/div).
Bandwidth: 20 MHz.
