Fairchild Announces Design For LCD TVs With 90% Efficiency

October 22, 2008 by Jeff Shepard

Fairchild Semiconductor’s Global Power Resource SM (GPR) design center in Japan has developed a design for LCD TVs that achieves 90% efficiency. The new design reduces the traditional four layers of PCB board to two, by utilizing the highly integrated FAN5069 and N-Channel MOSFET products.

The FAN5069 combines a Pulse-Width-Modulated (PWM) controller and a Low Drop Out (LDO) linear regulator controller in a single package to provide high efficiency over a wide range of load current. Efficiency is further enhanced by using low-side MOSFETs with low R_DS(ON) to sense current. The N-Channel MOSFETs reduce switching losses and optimize conduction losses. Both products are highly integrated to increase system efficiency and reduce component count.

"We’re very pleased to be able to offer our customers immediate and highly technical support and advice through our Global Power Resource design centers," said Greg Helton, President, Fairchild Semiconductor Japan. "Developing close customer relationships are crucial to Fairchild, and our GPR centers offer a unique service by collaborating with customers to provide highly integrated, energy-efficient designs."

Fairchild’s design centers, located in Germany, Korea, Taiwan, China, South America and the United States, are part of the company’s Global Power Resource, offering system power design, online design tools, evaluation boards, tutorials and joint research and development labs worldwide.
