Figure 5 - The circuit in figure 5 is designed to provide loss-less output short detection by detecting the DC voltage
across the inductor and shutting down the MOSFET and entering HICCUP mode. Note that the current limit point
is a function of the inductor resistance and in this application with approximately 8m
resistance the peak CL is
set at 10A. See application note on how to set the current limiting threshold.
TYPICAL APPLICATION
5V to 3.3V with loss-less short circuit protection (Output UVLO detection)
