Alpha Microelectronics A3130
The a3130 is a universal DSP-based PFC solution to be used in applications requiring power factor values close to unity. The controller is based on the boost topology and is fully softwarecontrolled. The PFC algorithm is loaded from an on-chip non-volatile memory for standalone operation or can be uploaded to the DSP core using a two-wire interface.| Part No. | A3130 |
