Cirrus Logic’s digital Power Factor Correction (PFC) controllers not only exceed the performance of legacy analog solutions, but do so at a competitive system price point for high volume, cost sensitive applications. These controllers support applications such as DTVs, PCs, Notebooks, fluorescent and LED lighting systems, and many other AC/DC products.
These controllers simplify system designs by reducing external component count by up to 30% and lowering the overall size and form factor, while at the same time improving performance and efficiency across all load conditions, with a distinct advantage in light load conditions. The future of power management is digital. Choose Cirrus Logic Digital PFC solutions for your next generation AC/DC power supply designs.
