Cirrus Logic's EXL Core: Smarter, Greener Energy Products

The CS1500 and CS1600 are the first in a new generation of digital Power Factor Correction (PFC) ICs to enable applications such as power supplies and fluorescent ballast systems to meet or exceed strict global regulations for energy efficiency.

Featuring Cirrus Logic’s new EXL Core™ architecture, with its currently 53 patented and patent-pending digital algorithm technologies, the CS1500 and CS1600 have the advantage over analog products of being able to intelligently solve increasingly complex power management challenges. Through its patent-pending digital noise shaping technology, both the CS1500 and CS1600 enable reduced-sized EMI filters, which cut the need for additional high-priced components and circuitry.

These digital ICs improve energy efficiency across all load conditions, with a distinct performance advantage in light load conditions, and simplify system designs by reducing external component count by more than 30 percent.
