Part Number: TPS55165-Q1
Tool/software: TINA-TI or Spice Models
I am trying to simulate TPS55165-Q1 in fixed 12V output in pspice, when I try to connect BST1/BST2 to cap as recommended in the datasheet, I get an error saying the pin is floating , I have tried running in multiple machines but the issue remains same, Please see the screenshot below,
N03722 is the node name for the wire connected to BST1, N03726 is for BST2.
When I try to connect it without cap, it works fine till 3ms and output travel back in time at 12V constant. i.e., out is 12V like I want but in time 3ms-0ms,which shouldn’t be possible. I have attached project files fyr.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Abhishek Tripathy:
I appreciate you response. I have used SPB 16.6 ( cadence 16.6) to draw the circuit, I tried simulating without using caps at those pins, I would get 12V at 1.2ms but from there I observe output in reverse direction.
I have attached the waveform fyr.
I have used the same file to simulate the below response
even when I connect BST1 and BST2 directly I get the same response
In reply to Sainath d:
I have attached the cadence 16.6 files again.lm55165-Q1.zip
I simulated the project shared by you. It runs absolutely fine. Please find results below.
I feel that there is some issue with loading the large data file in AMS simulator on your system.
I hope this clarifies your query.
Thanks & Regards,
