A 7.5 - 42V Input High-VCR Monolithic DC-DC Converter Using Stacked Isolated SC Cores

A fully integrated switched-capacitor DC-DC power converter that converts input voltages up to 42 V into 3 V is presented. The converter achieves a wide input operating range with multiple VCRs based on stacking of several isolated switched-capacitor converters. Stacking simplifies the design to a low voltage unit converter with only a few VCRs, while the wide input range high voltage converter achieves the efficiency of the unit converter. The DC-DC converter is designed in a 0.35 µm CMOS technology and achieves an output power of 2.1 mW
