A step-up converter based on an integrated transformer, comprising a self-resonating oscillator circuit that has inductive elements constituted by primary and secondary windings of at least one first transformer, the self-resonating oscillator circuit being powered by an external supply voltage.

Integrated transformer based step-up converter

A hybrid inductive-capacitive charge pump provided with a driving stage that comprises a step-up converter and a buffer capacitor, and a cascade of charge pump stages; the first stage of the stage cascade is connected to a power supply and the last stage of the stage cascade is connected to an output of the charge pump circuit; the charge pump circuit comprises elements for activating alternately the charge pump stages, transferring charge from one stage of the cascade to the next stage of the cascade, each stage of the cascade of charge pumping stages comprising a pass transistor and a capacitor.
