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).
