DIGITAL CURRENT SENSING IN POWER CONTROLLER

摘要

Some embodiments include apparatus and methods having a node to provide a signal, and a control unit arranged to control a value of an output voltage at an output node on an output path based on a duty cycle of the signal and a value of an input voltage. The control unit can also be arranged to cause a change in a resistance on the output path in order to determine a value of a current on the output path based at least on the change in the resistance.
