Error
Peak current limit setting
is too low for the desired
voltage and frequency.
Setting conflict. Peak
current limit setting too
low to support requested
voltage and frequency.
LMX has a minimum peak
limit because it affects
output inductor current
and at high frequencies, a
circulating current
proportional to the
voltage and frequency
occurs.
Increase the peak current
limit setting
