TPS51397A: VFB accuracy

Part Number: TPS51397A
Other Parts Discussed in Thread: TPS51362

Hi team,

We are evaluating TPS51397A to replace TPS51362. According to datasheet, VFB accuracies are provided as below.

TPS51362:  ±1.0% (-10°C to 85°C)

TPS51397A: ±1.0% (25°C), ±1.5% (-40°C to 125°C)

We would like ±1.0% (-10°C to 85°C), but also want to know how TPS51397A changes by temp. Do you have VFB accuracy vs. temp curve?  

Best,
Zeming
