一种具有自动相位分配的单电感多输出自动升降压DC-DC变换器

A single-inductor multiple-output (SIMO) converter with auto-buck-boost feature is presented in this paper. A seamless auto-buck-boost scheme for SIMO dc–dc converter using time-multiplexing control is proposed. Additionally, with the proposed first-order phase-locked loop (FOPLL) and autophase allocation, this circuit solves the problem of unbalanced loadings of different channels, and it also ke...
