Driver controller with internally calculated average output current

摘要

Methods, devices, and integrated circuits are disclosed for a driver controller that internally calculates average output current. In one example, a method includes receiving an output voltage of an output line. The method further includes performing a calculation of an average output current at the output line based at least in part on the output voltage. The method further includes controlling an interval timing of a switch based at least in part on the calculation of the average output current at the output line, wherein the switch is configured for switching current to the output line.
