I'm using the TPS61087 boost converter to generate 13.7V starting from 5V input.
As a load I have a big capacitor, 1000uF electrolytic, in parallel to 2x22uF ceramic capacitor.
In order to slow down the initial charging phase, I'm using a 2.2uF Css capacitor.
Unfortunately it seems the soft start feature doesn't work. In attachement the oscilloscope screenshot:
orange - enable signal
yellow - output voltage
blue - input current
The initial current peak does not respect the soft start limitation. It is not always repeatable.
Thank yuo very much for any suggestion or explanation
