TINA/Spice/TPS732: start-up time

Guru 29690 points
Part Number: TPS732
Other Parts Discussed in Thread: TINA-TI

Tool/software: TINA-TI or Spice Models

Hi Team,

There is "TPS73250 TINA-TI Transient Reference Design" in the following link.
http://www.ti.com/product/TPS732/toolssoftware
The result of ramp-up time using above is the following (~150us) however datasheet shows 600us(typ).






There is large difference between TINA-TI result (~150us) and electrical characteristc (600us) in datasheet.
I changed RL and Cout of TINA-TI schematic same as test conditions of tSTR however the result is almost the same.

Sould we consider electrical characteristc in datasheet as correct?

Best Regards,
Yaita
