Classifcation Load Current of LTC4278


we got some question regarding the Classifcation Load Current of LTC4278; could you kindly help on it; please?

As shown in figure 1; if the PSE input port voltage is between 12.5V to On; the Classifcation Load Current  will constantly be there?

In our test shown in Figure 3; we found when port voltage <=33V; 40+ mA current into LTC4278; which cause the chip temp rising to 85C @ 25C ambient temp.

If so; any method to relieve this issue? Many thanks!
