Part Number:TPS40170
Tool/software:TINA-TI or Spice Models
Hello,
Our customer evaluating TPS40170 and they have questions.
1. TPS40170 cannot startup, however, due to adding gate resistor 5.6ohm(same value as EVM), it can be fixed.
2. TPS40170 cannot startup, however, due to changing Css from 2.2nF to 47nF, it can be fixed.
(in 1, Css=2.2nF fixed and in 2, no gate resistor attached )
They had use TINA-TI to confirm whether these action is reasonable or not, however, they could not confirm.
Attached TINA-TI circuit(modified from tsc file on the web) can startup without gate resistor, and Css=2.2nF.
Is there any problem for their usage or in macro model ?
Thanks and best regards,
Hiro
