Hello
LM5121 data sheet Fig 24 describes that Vcc starts up after UVLO exceeds 0.4V.
However, LM5121 EVM ( input is 9V/ output=12V/ Io=0.1A ( nothing of components changed )),
it is observed as when UVLO exceeds 1V, Vcc starts up.
( capture is attaced )
Would you please confirm and advise the reson why ?
Thank you and with my Best Regards
