Thanks for all suggestions. It turned out to be dodgy connection on the voltage feedback resitor divider. All measurements were OK, but today I just blew off both resistors with hot air to check them separately, then soldered both of them back and it works. Shame on me. Quote from: Niklas on November 28, , pm I cannot see the uF output capacitor and possibly only one of the 1uF on the output in the layout overview. The datasheet mentions low ESR type capacitors, so those capacitors should be located somewhere close.
