A fully integrated switched-capacitor DC-DC converter with 32-phase interleaving is implemented in 0.374 mm2 of a 32 nm SOI process. The converter can be reconfigured into three topologies to support 0.5 to 1.2 V output from a 2 V input supply, and achieves a maximum efficiency of 77% at an output power density of 0.55 W/mm2.
