Hello,
The datasheet says
The MP1542 is a current mode step up converter with a 2A, 0.18Ω internal switch to provide a highly efficient regulator with fast response.
Would it correct to assume that the IC can handle 2A continuous current, transients or just the capability of the MOSFETs to switch large current. The Web Designer tool spits out an error when setting Iout to 2A, the max current 600mA.
