Austin, Tex.Designed for energy-related markets, Cirrus Logic Inc. has launched a new product line that includes the CS1500 and CS1600 digitally controlled, discontinuous conduction mode (DCM), active power factor correction ICs for use in power supplies rated up to 300 watts.
The CS1500 addresses power supplies such as laptop adapters, digital TVs and PC power, while the CS1600 targets electronic lighting ballasts.
Cirrus Logic is touting its new line of digital power factor corrections (PFC) controller ICs as the first to surpass analog PFCs on performance and price. According to Cirrus Logic, both ICs are priced on par with analog PFCs, while also lowering the overall bill of materials by up to $0.25.
Featuring its EXL Core architecture, the CS1500 and CS1600 have the advantage over analog products 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.
Additionally, 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, according to the company.
Pricing: $0.30 in 1 million unit quantities.
Availability: Now in an 8-pin SOIC package.
