Circuit and method for adjusting an inductor current in a power converter

A single inductor multiple output (SIMO) power converter comprising:

• a SIMO power stage configured output a plurality of output voltages, the SIMO power stage including a plurality of switches that are configurable to place an inductor in a charging state, a discharging state, or a freewheeling state during a cycle of the SIMO power stage;
• a state machine that is coupled to the SIMO power stage, the state machine configured to output switching signals to configure the plurality of switches according to a state of the cycle;
• and
• an analog control coupled to between the SIMO power stage and the state machine, the analog control configured to compare sensed signals from the SIMO power stage to thresholds, and based on the comparisons, configure the state machine to output switching signals according to the state of the cycle, the analog control including a peak-current threshold control circuit configured to adjust a peak-current threshold according to the plurality of output voltages when the inductor is in the freewheeling state, the peak-current threshold corresponding to a peak current that the inductor is charged to during the charging state.
