Abstract
A method may include monitoring a current through a power inductor of a boost converter and detecting when a mathematical integral of a difference between the current as monitored and a desired average current for the power inductor is equal to zero. Another method may include in a first mode of operation of a boost converter, controlling switching behavior of switches of the boost converter to regulate an output voltage generated by the boost converter and in a second mode of operation of the boost converter, controlling switching behavior of switches of the boost converter to regulate an input current received by the boost converter. Another method may include monitoring a current through a power inductor of a boost converter and detecting when the current as monitored exceeds a maximum current for the power inductor.
