San Jose, Calif. — Fairchild Semiconductor's Global Power Resource (GPR) design center in Japan has developed a solution for LCD TVs that achieves 90 percent efficiency. The new design reduces the PCB board layer count from four to two, by using the highly integrated FAN5069 and N-Channel MOSFET products.
The FAN5069 combines a pulse-width-modulated (PWM) controller and a low dropout (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 RDS(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.
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. The center in Japan provides designs solutions for power applications such as games, digital display panels and white goods markets.
