Abstract
A switching loss is reduced by reducing a deviation from the operational principle of zero-volt switching (ZVS). A semiconductor integrated circuit includes high-side switch elements Qand Q, a low-side switch element Q, and a controller CNT. A decoupling capacitance Cin is coupled between one end of a high-side element and an earth potential, and the high-side element includes the first and second transistors Qand Qcoupled in parallel. In changing the high-side elements from an on-state to an off-state, CNT controls Qfrom an on-state to an off-state by delaying Qrelative to Q. Qand Qare divided into a plurality of parts inside a semiconductor chip Chip, a plurality of partial first transistors formed by dividing Qand a plurality of partial second transistors formed by dividing Qare alternately arranged in an arrangement direction of Qand Q, inside the semiconductor chip Chip
