Figure 13: Input reflected ripple current, is, through a 4.7 µ H source
inductor at 75V input voltage and rated load current (50 mA/div). (See
Figure 11).
Figure 14: Output voltage ripple at nominal input voltage and rated load
current (200 mV/div). Load capacitance: two 6.8µ F ceramic capacitors
and 15µ F tantalum capacitor. Bandwidth: 20 MHz. (See Figure 11).
Figure 15: Output voltage response to step-change in input voltage
(1000V/ms). Load cap: no output capacitance. Ch 1: Vout (2V/div), Ch 2: Vin
(20V/div).
Figure 16: Load current (20A/div) as a function of time when the con-
verter attempts to turn on into a 1 mW short circuit.
