Cirrus Logic's CS1501/1601 are high-performance variable frequency discontinuous mode, active digital power factor correction (PFC) controllers. The series features Cirrus Logic’s EXL Core® technology that brings innovative digital energy control which elevates performance and reduces total solution size. The unique digital architecture of our PFC controllers enables a reduction in the boost inductor value (LB), the size of the EMI filter stage and many external passive components. Variable on-time/ variable frequency algorithm is used in achieving close to unity power factor and spreading the EMI frequency spectrum, thus reducing the conducted EMI filtering requirements. 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, overcurrent, overpower, open and short circuit protection, over temperature, and brownout) help guard the device during abnormal transient conditions.
