In systems with multiple phase spreading.” switching power supplies, the switching phase between power supplies may need to be Synchronized Phase Spreading in the manipulated to reduce undesired effects in a ZL2005 system. These undesired effects include large peak current drawn from the input voltage and high Pin-Strap Configuration……
