TPS61071-Q1: About TPS61071-Q1

Part Number: TPS61071-Q1

Hi

I have three questions about TPS61091-Q1.
1.
   The VFB is typ 500mV(±10mV) at Ta=25℃ in datasheet.
   Could you tell me the VFB over temperature? 
2.
   Is the L1 of equation (3) and (4) the maximum average inductor current?
3. 
   It is written that "6-pin thin SOT package (DDC) is RθJA = 130°C/W"  and "Specified regulator operation is assured to a maximum ambient temperature TA of 85°C" in  10.3 Thermal Considerations,.
But RθJA is 139.1℃ in thermal information and Ta_max is 105℃ in Recommended Operating Conditions.
Which is correct respectivity?
  Is the PD(max) of equation(8) max loss to be able to lose in specified Ta?
Best regards,
Yokota
