Dear all,
I measure my dc to dc converter ( 3.3 -> 1.8 ) . My design is load current is
0.8A. But I measure my output will have a spike at load current of over 0.4A. This
spike will be sometime the peak of 2.8. This condition my OCP is off. Why do my
load current can not over 0.4A? The other question. Is it load current is larger, the
output ripple is larger? Why? The inductor's have a DC current of the spec. If I use
dc current is over 1A. Is it 1A at any frequency? Thanks.
