I need a DC-DC converter from 12V to 3.3V and 4A. So I decided for swiching regulator L5988D.
My circuit is the same as in .My problem is, that switcher begins turning itself off at current cca. 0.8A. I even removed R_LIM, so there is no current limit.What am I doing wrong? #l5988d-switcher-turning-off
