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 10H source impedance and 47F elec-
trolytic capacitor (200 mA/div). (See Figure 13)
Figure 15: Input reflected ripple current, is, through a 10 H source
inductor at nominal input voltage and rated load current (10 mA/div).
(See Figure 13)
Figure 16: Output voltage ripple at nominal input voltage and rated
load current (50 mV/div). Load capacitance: 1F ceramic capacitor
and 10F tantalum capacitor. Bandwidth: 20 MHz. (See Figure 13)
Figure 17: Output voltage vs. load current showing typical current limit
curves and converter shutdown points.
Figure 18: Load current (10A/div) as a function of time when the con-
verter attempts to turn on into a 10 mW short circuit. Top trace is an
expansion of the on-time portion of the bottom trace.
