Posted on July 30, 2013 at 10:46I 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?
