With internal pulse-by-pulse current limiting and a fixed soft start time, there is a maximum output capacitance
which may be used before startup problems begin to occur. If the output capacitance is large enough so that the
device enters a current limit protection mode during startup, then there is a possibility that the output will never
reach regulation. Instead, the TPS5438x simply shuts down and attempts a restart as if the output were
short-circuited to ground. The maximum output capacitance (including bypass capacitance distributed at the
load) is given by Equation 3:
