Catalyst Semiconductor Inc., a supplier of analog, mixed-signal and non-volatile memory semiconductors, and Leadis Technology Inc., an analog and mixed-signal semiconductor developer of color display drivers, LED drivers, and audio ICs for mobile and consumer electronics devices, have announced a partnership on Catalyst's patent-pending Quad-Mode LED driver technology. Under the partnership agreement, Leadis will license Catalyst's Quad-Mode charge pump technology and receive rights to integrate the architecture in upcoming LED driver products.



"This partnership marks the recognition by both Leadis and Catalyst that the Quad-Mode adaptive fractional charge pump architecture delivers the next leap forward in LED driver efficiency for today's portable products," said Gelu Voicu, Catalyst Semiconductor's President and CEO. "Catalyst is pleased to partner with Leadis as they are a recognized leader in the small color display driver IC market. This relationship further validates the unparalleled performance of the Quad-Mode architecture."



Catalyst's Quad-Mode charge pump LED driver architecture delivers 10 percent higher efficiency in a 65 percent smaller package compared to competitive similar technologies through the addition of a 1.33x fourth pump mode, augmenting the existing 1x/1.5x/2x pump options. The 1.33x mode provides a higher efficiency alternative to the industry-standard 1.5x mode typically utilized when the system battery voltage is not sufficient to drive the LED in 1x mode. Quad-Mode LED drivers combine the efficiency levels of inductive boost converters and the simplicity of charge pumps, without adding cost, components or board space. These significant power and space savings give today¡¦s advanced handheld device designers an enhanced level of system performance to meet consumer demand for lower cost and longer battery life portable products.



The Quad-Mode LED driver partnership between Leadis and Catalyst marks the dedication of both companies to ensure the deployment of Quad-Mode technology throughout the global handheld display industry. As a result of the partnership, opportunities may be opened up for customers to have multiple sourcing options for this innovative LED driver architecture. The companies also plan coordinated marketing and sales activities to build awareness of the significant battery and space savings realized through the use of Quad-Mode products.



"We are very pleased to partner with Catalyst to bring their innovative Quad-Mode charge pump architecture to market," said Leadis Technology President and CEO, Tony Alvarez. "Quad-Mode LED drivers together with Leadis' new PowerLite line of LCD display drivers comprise a compelling solution and breakthrough in power savings for today's advanced mobile display designs."
