ST offers a complete product portfolio, including both continuous and transition operating mode, for a wide range of applications.
Power factor correction synchronizes the current demand with the AC voltage waveform, so reducing the harmonic noise injected back into the power line. As a result, there is more total power available and higher efficiency in energy transportation, the transformer size can be reduced, there are fewer disturbances on the line and so it is compliant with EN61000-3-2 regulation which is mandatory for input powers greater than 75 W.
