Abstract
A switched current control module comprises a hysteretic control component arranged to receive high and low threshold values and an indication of a current flow through a load, and to output a switched current control signal based on a comparison of the current flow indication to the high and low threshold values. A threshold generator is arranged to generate the high and low threshold values based on a base threshold value and a hysteretic excursion value. A base threshold value generator is arranged to generate the base threshold value based on the current flow indication and a setpoint value. A hysteretic excursion value generator is arranged to receive an indication of a switching frequency of the switched current control signal output by the hysteretic control component, and to generate the hysteretic excursion value based on the indicated switching frequency of the switched current control signal.
