24V input on TPS23841 as PoE

Hello,

Regarding to the PoE on TPS23841, my customer is asking about input range.

According to the datasheet, the input range is 21.5 V to 57 V and they will use 24V as input.

But I think that the output range of PoE is 44.0 to 57.0V.( IEEE 802.3af)

(Question)

(1) Is this device supported 24V input as PoE application?

(2) if it’s available, how it is supported?

Regards,
