Overview

com a3131 general features The a3131 is a universal DSP-based PFC solution with Switching-mode Power Supply to be used in applications requiring power factor values close to unity and highly efficient DC power supply.
Typical application areas for the a3131 are high-power DC motor controllers and lighting systems.
The power factor controller (PFC) is based on the boost topology and is fully software-controlled.
The PFC algorithm is loaded from an on-chip non-volatile memory for stand-alone operation or can be uploaded to the DSP core using a two-wire interface.
The switching-mode power supply controller (SMPSC) is based on the flyback topology with current feedback, and its ...
