Fairchild Semiconductor Green FPS e-Series: Power switch conserves energy using valley-switching technique

The Green FPS (Fairchild Power Switch) e-Series touts high energy efficiency and reliability and suits DVD players, set-top boxes, LCD monitors, and other 25W and lower power-supply designs. Using the vendor’s proprietary “valley-switching” technique, the devices combine the functions of avalanche-rated SenseFETs, current-mode-PWM (pulse-width-modulator) ICs, and various protection features. The power switch has a 0.2W standby-power-consumption at no load conditions and less than 1W power-consumption at a 0.5W load. Units in the Green FPS e-Series costs 84 cents each.
