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

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. ?? 2018 IEEE

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

This paper presents a reconfigurable SIMO system with 10-output dual-bus DC-DC converter having two buses for heavy and light load outputs, respectively. The converter controls the load condition for each bus to be well balanced. Under diversified load condition, a group allocator assigns each output to the corresponding bus properly depending on its load current. Due to such load balancing function, severe regulation issues which could occur under diversified load condition are resolved with output voltage ripples below 25mV, and over 81% efficiency is achieved under wide range of load (0-300mA). ?? 2016 IEEE
