margin goal of 8dB or greater. Refer to the LTC3311 data
sheet and LTPowerCAD for more information on choosing
the required components.
The soft-start of the multiphase regulator is controlled by
a single cap, C12, on the master phase. After the regulator
is in regulation the SSTT pin can be used to monitor the
