Hi,
From the datasheet,we see the relationship between IOUT and foldback current limit. First, IOUT reaches current limit which is 1.5A. Then Vout decreases to 0.4*3.3V, IOUT is limited to short current which is 680mA typically.
However, the waveform we tested is different from what is shown above.
We used E-load of which slew rate is 0.01A/us. IOUT is limited to 954mA finally. The value is out of range of current limit. I am confused about it. Could you give me any advice?
