HI
Currently using the TPS54610PWPR buck controller for 3V3 output from 5VDC supply. SS for the controller has been selected for a soft start of > than the device fixed SS of 3.35mS however i have noticed that at turn on the controller initially outputs a voltage for a short time period. Any thoughts ? SS cap charge up looks good. device data states that output is enabled once voltage has reached to 90% of set point . Looking at the output prior to LC filter , there appears to be a DC voltage rise followed by clear switching activity (couple of pulses) then turns off, turning back at 90% set point.
