2.3 Load Transients
Load transient response is shown in the following figures. The load step was applied to the 12VSB output. The input voltage was 390 VDC, and both P18V and S12V were unloaded. A system capacitance of 1000-μF was connected to 12VSB, and 100-μF was connected to P18V, respectively. Channel 2 shows the 12VSB output voltage, AC coupled. Channel 4 shows the 12VSB load current.
