The CS1500 is a high-performance Variable Frequency
Discontinuous Mode, active digital power factor
correction (PFC) controller. It features Cirrus Logic’s
EXL Core™ technology that brings digital energy
control innovation which elevates performance and
solves system design challenges in power supplies
used in notebook adapters, digital TVs and PCs.
enables reduced-size EMI filters and eliminates the
need for numerous passive components, delivering
the lowest PFC system costs available.
used to achieve close to unity power factor and shaping
the EMI noise spectrum, thus reducing the conducted
EMI filtering size and cost. The feedback loop is closed
through an integrated compensation network within the
IC, eliminating the need for additional external
components. Protection features (such as overvoltage,
overpower, open and short circuit protection, over-
temperature, and brownout) help protect the device
during abnormal transient conditions.
