A reconfigurable SIMO system with 10-output dual-bus DC-DC converter using the load balancing function in group allocator for diversified load condition

Abstract

Portable electronic devices require multiple supplies with relatively large difference in load currents, which causes serious problems when adopting a single-inductor multiple-output (SIMO) DC-DC converter. To resolve these problems, this paper presents a SIMO system with 10-output dual-bus DC-DC converter having two buses for heavy and light load outputs, respectively. Due to such load balancing function, regulation issues which could occur under diversified load condition are resolved.
