Green FPS e-Series for Power Efficiency and System Reliability in Flyback Power Supply Designs
Fairchild Semiconductor introduced the Green FPS e-Series, a 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 Fairchild’s proprietary valley switching technique, the devices raise power conversion efficiency by 1 percent and reduce EMI up to 5 dB compared to conventional hard-switch converter topologies. These highly integrated 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. Utilizing 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). These products meet or exceed the requirements of the joint IPC/JEDEC standard J-STD-020C and are compliant with European Union regulations now in effect.
