Abstract: PURPOSE: To provide a boost converter which suitably drives the capacitive load direct and is easily miniaturized with a simple circuit. CONSTITUTION: One terminal of an inductor L, which is connected to a supply rail VDD through a 1st switch SWA, is connected to an output node VOUT to which a capacitive load C is connected through a 1st discharge path (SWC+D1) and the other terminal of the inductor, which is grounded through a 2nd switch SWB is connected to the output node through a 2nd discharge path (SWD+D2).

Abstract: PURPOSE: To provide a boost converter suitable for driving a capacitive load directly with a relatively high voltage and which can be miniaturized easily through a simple circuit. CONSTITUTION: An inductor connected through a first switch SWA with a supply rail VDD has one terminal connected through a first discharge path (SWC+D1) with a capacitive load C and the inductor grounded through a second switch SWB has the other terminal connected through a second discharge path (SWC+D2) with an output node.

Abstract: A DC-DC boost converter for directly driving a capacitive load employs four switches for cyclically commuting the connection configuration of an energy storing inductor. First and second switches are driven at a relatively high frequency and provide an impulsive charge path of the inductor by connecting one or the other end to a power supply rail. Third and fourth switches are driven in phase opposition to each other at a relatively low frequency and provide a discharge path from one and the other end of the inductor, respectively, toward an output node of the circuit to which the capacitive load is connected.
