Abstract
A series capacitor buck converter includes a first half-bridge circuit including a first high side power switch (HSA) and first low side power switch (LSA) connected in series having a first switching node (SWA) therebetween which drives a first output inductor, a second half-bridge circuit including a second HS power switch (HSB) and second LS power switch (LSB) connected in series having a second switching node (SWB) therebetween which drives a second output inductor. A transfer capacitor (Ct) is connected in series with HSA and LSA and between the first and second half-bridge circuits. A first current source is coupled for precharging Ct with a charging current (I_in) and a second current source is coupled to Ct for providing an output current (I_out). A feedback network providing negative feedback forces I_out to match I_in.
