NOTE: If an electronic load is used, ensure that the output load is set to constant resistance mode
and not constant current mode.
NOTE: Measuring Current Limit values on the oscilloscope can easily cause 10% error from
anticipated values listed in Table 10.
NOTE: Since the pulse width of current can vary significantly with the VIN ramp rate, which varies
from one power supply to another, do not worry about matching the pulse widths of Figure 5
and Figure 6.
• The jumper setting for the different current limit test is shown in Table 10.
