Abstract
A circuit to control the peak current of a single inductor multiple output (SIMO) power converter operating in continuous current mode (CCM) is disclosed. The circuit generates a peak-current threshold signal that can be raised or lowered based on an error signal generated by comparing output voltages to their respective regulated levels. Additionally, the circuit can lower the peak-current threshold signal when an energy storage element of the SIMO power converter is in a freewheeling state. The lowering can occur at a rate that continues as long at the freewheeling state persists. The disclosed circuits and methods allow the peak-current threshold to converge on a level that facilitates the sufficient charging of the energy storage element to provide enough energy to the outputs but not excessive charging so as to increase ohmic loss associated with the freewheeling state.
