Abstract

See full text

Systems and methods are provided that may be implemented to provide a power supply with automatic overcurrent protection (OCP) point calibration and/or current sense resistor (Rsense) verification. The provided systems and methods may implement auto-calibration techniques on the secondary side of a power supply to achieve a more precise OCP point than is possible with conventional adapter technology, and in one example may implement auto trimming for OCP voltage threshold value.
