Abstract:

Previously reported switching DC-DC converters have feedback loops incorporating error amplifiers to regulate their output voltages. Hence, load variation affects the closed-loop response and should be considered in compensator design, which fundamentally limits the closed-loop performance of switching converters. In this paper, a load-independent converter with freewheeling current feedback, whose output is controlled by a comparator, is presented. This control method is very useful for single-inductor multiple-output (SIMO) converters [1-3].
