  • Abstract
    A 320 mW integrated switched capacitor DC-DC converter is realized in a 0.35 mum DMOS high voltage technology. This 10 stage converter generates 70 V from a 12 V voltage supply, at a maximum efficiency of 85.5% per stage. An on-chip control system varies the clock frequency from 0 to 35.4 MHz in order to regulate the output voltage at varying loads and supply voltages. Each of the stages uses an integrated capacitor of 74 pF. The total area of the chip is 6 mm2.
