Part Number: LM5157 Dear TI team,
I am using IC LM51571RTER as boost converter (Input=10 V, Output=20 V). I have applied 1.2 V across Enable pin of IC (Enable threshold is 0.7 V max) but I am not able to turn on Boost IC.
Note: Bias pin voltage=10 V

Hello TI Engineers,
I was using my LM5157 SEPIC circuit when all of a sudden it stopped working. The schematic is shown below and the layout is very similar to the LM5157 SEPIC Evaluation Board…
Hi Lin,
it looks like this thread is identical to this one:
(+) LM5157-Q1: Sepic converter design - Power management forum - Power management - TI E2E support forums
So, i will close this one an put my response on the other thread.
Best regards,

Part Number: LM5157-Q1 I want to know which simulation model of LM5157-Q1 support worst case analysis. If the flyback works at the worst condition, will the model reflect the real accuracy of voltage, especially the output?
Thanks!
