Abstract:
A system for controlling a current in a power converter configured to generate an output voltage may include a control loop having a plurality of comparators, each comparator having a respective reference voltage to which the output voltage is compared, a digital controller configured to calculate one or more pre-seeded control parameters for the current, and an analog state machine configured to, based on outputs of the plurality of comparators, select control parameters for controlling the current. The control parameters may be selected from the pre-seeded control parameters, control parameters for controlling the current to have a magnitude of zero, and control parameters for controlling the current to have a maximum magnitude.
