# Question about current output of a DC-DC stepdown converter

If we have a solar panel of 5V and we want to keep voltage on the output to 3V, what current we are getting on the output? The same as in the input? Or a different one?

$P_{out} = P_{in} \cdot 80\%$
$3I_{out} = 5I_{in} \cdot 0.8$
$I_{out} = 1.33I_{in}$
