TPS54560B: About efficiency of Inverting Back-Boost Converter.@SVLA317B

Part Number:TPS54560B

Hi team.

I want to make supply voltage from TPS54560B by topology listed in SLVA317B .

The specification of this power supply is as follows...

Input voltage : 48 V

Output voltage : -7 V

Output current : 1.5~2.0 A

So, I have one question.

Do you have efficiency data in this topology?
