Figure 13: Test Set-up Diagram showing measurement points for Input Terminal
Ripple Current (Figure 14), Input Reflected Ripple 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 4.7µH source impedance and 220µF electrolytic
capacitor (Ch.1 500mA/div, 2µs/div). (See Figure 13).
Figure 15: Input Reflected Ripple Current, is, through a 4.7µH source inductor
at nominal input voltage and rated load current (10mA/div, 2µs/div). (See Figure
13).
Figure 16: Output Ripple voltage at nominal input voltage and rated load
current (100 mV/div, 2µs/div). Load capacitance: one 1.0µF ceramic capacitor
and one 15µF tantalum capacitor. Bandwidth: 20 MHz. (See Figure 13).
