2.9 Output current limit characteristics – Constant Power Mode
Operation at higher currents but constant power is possible from 72% of Voltage range (138% of max.
current) declining to 100% of maximum current at 100 % of voltage range.
Output current limit
characteristics are applicable for Source and Sink operating Modes, Refer to Figure 2-4. Full-scale current
rating for different power models is given in Table 2-1.
