  ABSTRACT: This paper describes design techniques to maximize the efficiency and power density of fully integrated switched-capacitor (SC) DC-DC converters. Circuit design methods are proposed to enable simplified gate drivers while supporting multiple topologies (and hence output voltages). These methods are verified by a proof-of-concept converter prototype implemented in 0.374 mm² of a 32 nm SOI process. The 32-phase interleaved converter can be configured into three topologies to support output voltages of 0.5 V-1.2 V from a 2 V input supply, and achieves 79.76% efficiency at an output power density of 0.86 W/mm² .

  ABSTRACT: 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.
