(L6730). With the L6730B there is the possibility to set the HICCUP mode or the constant
current mode after the soft-start acting on the multifunction pin CC/O/U. With the L6730 the
low-side MOSFET(s) management after soft-start phase depends on the S/O/U pin state
(see related section). If the sink mode is enabled the converter can sink current after soft-
start (see
