Cirrus Logic CS1501 / CS1601 Digital PFC Controllers

Cirrus Logic CS1501 and CS1601 digital PFC controllers feature super light-load efficiency, top-end power factor correction, and unsurpassed THD (total harmonic distortion). These high-performance Variable Frequency Discontinuous Mode active digital PFC controllers feature Cirrus Logic EXL Core® technology that enables intelligent and adaptive switching. The CS1501 and CS1601 operate at switching speeds up to 70kHz. These digital PFC controllers have current sense and zero crossing detect functionality along with a host of protection features, including brownout protection, overvoltage protection, and overpower protection with shutdown. The Cirrus Logic CS1501 digital PFC controller is designed for switching mode power supply (SMPS) applications. It actively manages the power factor correction while achieving high efficiency over a wide load range. The CS1601 delivers the lowest PFC system cost in electronic ballast applications.
