Dear Ti Team:
I got a problem with LM5160-Q1.
First, the current limit is 2.5A typ. When Vin is more then 6v. The operation is normal. The Isw reach 2.5A , IC operation at short circuit mode.
But , when Vin equal 5v, the current limit become about 5.2A.
The input current become very high. Can you explain it? Thanks.
Spec. and The waveform below
