Solutions
For over a decade, Cirrus Logic has been a proven leader in the energy metering and monitoring market.
Combining advanced Delta-Sigma technology with expert digital signal processing, Cirrus Logic offers
a broad product family with superior performance to support a wide variety of application requirements.
Enabled by Cirrus Logic’s EXL Core architecture, the CS1501 and CS1601 series of digital PFC controllers
intelligently solve power management challenges, allowing for smaller total solution size and better
efficiency and THD across load conditions. Ideal for power supplies up to 300 W, applications include
commercial lighting, digital TV, notebook adapters, desktops and servers.
Cirrus Logic has set the standard for seismic ICs — including complete data acquisition system solutions of best-
in-class single-sensor and multi-sensor chipsets. Cirrus Logic's products for energy exploration applications include
hydrophone and geophone amplifiers, high-fidelity Delta-Sigma modulators, and seismic digital filters plus test DAC.
Solving the challenges in the LED lighting market is the newest conquest in energy products from Cirrus Logic. Through the unique
digital algorithms within TruDim technology, a new lineup of digital LED controllers has effectively solved the LED lamp's most
glaring challenge: dimmer compatibility. Cirrus Logic's 1610 LED controllers have been tested to provide near 100 percent dimming
compatibility with a wide variety of dimmers representing the vast majority of the installed base. New LED controller products
coming in 2012 will also help LED manufacturers improve LED color temperature quality and focus on system cost reduction.
