Abstract
A voltage conversion circuit includes an N-level conversion unit and N−1 DC-DC conversion units. The N-level conversion unit includes N output terminals at different levels. A first input terminal of an MDC-DC conversion unit is connected to an Moutput terminal of the N-level conversion unit, and a second input terminal of the MDC-DC conversion unit is connected to an (M+1)output terminal of the N-level conversion unit. An output level of the Moutput terminal and an output level of the (M+1)output terminal are adjacent levels. N and M are positive integers and satisfy N≥3 and 1≤M<N.
