Other Parts Discussed in Thread: TL431
Hello,
there seems still to be the issue with start-up response of the ATL431B model which is different to the start-up response shown in the datasheet. The issue was also part of a discussion about the ATL431A model: https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/516726/atl431-spice-model-problem?tisearch=e2e-sitesearch&keymatch=ATL431%25252520Model#
For my simulation I used the "ATL431B Unencrypted PSpice Transient Model" from the download page and imported it to LT-Spice: https://www.ti.com/product/ATL431#design-development
The following picture shows the simulation result from LT-Spice with the test circuit of the datasheet. I also attached the LT-Spice simulation file.
Is there a way to fix this problem?
