A hybrid three-switch DC-DC step-up power converter for on chip applications is proposed. It is shown that the hybrid-three switch step-up converter can offer advantages such as reduced size of magnetic components, reduced MOSFET voltage stresses, improved closed loop control and can offer high efficiency compared to a standard boost converter of the same IC package size. These improvements are made possible by adding a flying capacitor that reduces the voltage stresses on the switches and decreases the inductor size by reducing the volt-second across the inductor. The converter is implemented as an integrated circuit built in a 0.25[mu]m 5V CMOS process. Experimental verification shows the gains.
