ec78ec78ic603a.jpge_arrows.jpgFairchild Semiconductor introduced the Green FPS e-Series, a new family of Fairchild Power Switch (FPS) products that provide high energy efficiency and system reliability in DVD player, set top box, LCD monitor and other 25W and lower power supply designs. Based on a proprietary valley switching technique, the Green FPS products raise power conversion efficiency by 1 percent and reduce EMI up to 5 dB compared to conventional hard-switch converter topologies, according to the company. These integrated FPS devices combine the functionality of a fully avalanche rated SenseFET, a current mode pulse width modulation (PWM) IC and various protection functions, simplifying design and improving system reliability. Using advanced burst mode operation, the Green FPS e-Series devices meet stand-by power regulations by reducing standby power consumption to below 0.2W at no load conditions (below 1W at 0.5W load). By employing an advanced control technique, the Green FPS e-Series products allow power converters to operate with narrow frequency variation while maintaining valley switching operation.
