LCD TV solution boasts 90% efficiency

Fairchild Semiconductor's Global Power Resource (GPR) design centre in Japan has come out with an LCD TV design that is claimed to be 90 per cent efficient. The solution trims down the traditional four layers of PCB to two, by utilising the highly integrated FAN5069 and N-Channel MOSFET products. Combining a PWM controller and an LDO linear regulator controller in a single package, the FAN5069 promises 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 optimise conduction losses. Both products are highly integrated to increase system efficiency and reduce component count.

This GPR centre in Japan provides designs solutions for power applications such as games, digital display panels and white goods markets.
