Abstract
A switching current regulator controls a load current flowing through a load. The switching current regulator switches a switch to an ON state after applying a regulating signal to the switch. During an integration period while the switch is in the ON state, the switching current regulator integrates an output voltage based on a sense voltage based on the load current and a reference voltage; at the end of the integration period, the switching current regulator outputs an integrated output voltage. The switching current regulator compares the integrated output voltage to a predetermined value. Based on a result of comparing the integrated output voltage and the predetermined value, the switching current regulator adjusts the regulating signal.
