The unique digital architecture of the CS1500
enables reduced-size EMI filters and eliminates the
need for numerous passive components, delivering
the lowest PFC system costs available.
Variable on-time / variable frequency algorithm is
used to achieve close to unity power factor and shaping
the EMI noise spectrum, thus reducing the conducted
