a3130 general features The a3130 is a universal DSP-based PFC solution to be used in applications requiring power factor values close to unity. Typical applications are high-power DC motors and lighting systems. 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. Highlights:  Fully reconfigurable digitally-controlled power factor controller in CMOS technology  On-chip AC-phase-locked sinusoidal 45...65Hz oscillator to improve AC-line noise rejection  High accuracy through on-chip 10bit ADC and dedicated RISC processor  Achievable high efficiency (>95%) and power factor (>0.99)  [ ... ]
