Technical Specification
Figure 14: Input Terminal Ripple Current, ic, at full rated output cur-
rent and nominal input voltage with 10H source impedance and 47F
electrolytic capacitor (50 mA/div). See Figure 13.
Figure 15: Input reflected ripple current, is, through a 10 H source
inductor, using a 47F electrolytic input capacitor (5mA/div). See
Figure 13.
Figure 16: Output voltage ripple at nominal input voltage and rated
load current (20 mV/div). Load capacitance: 1F ceramic capacitor
and 15F tantalum capacitor. Bandwidth: 20 MHz. See Figure 13.
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 17: Output voltage response to step-change in input voltage (48V
to 75V), at 45A load current. Load cap: 10F tantalum capacitor and 1uF
ceramic cap. Ch 1: Vout (100mV/div), Ch 2: Vin (20V/div).
