Abstract :

[en] A 320mW integrated switched capacitor DC-DC converter is realized in a 0.35μm DMOS high voltage technology. This 10 stage converter generates 70V from a 12V voltage supply, at a maximum efficiency of 85.5% per stage. An on-chip control system varies the clock frequency from 0 to 35.4MHz in order to regulate the output voltage at varying loads and supply voltages. Each of the stages uses an integrated capacitor of 74pF. The total area of the chip is 6mm2. © 2009 IEEE.
