Fairchild Semiconductor's Green FPS(TM) e-Series(TM) Optimizes Power Efficiency and System Reliability in Flyback Power Supply Designs.Fairchild Power Switch (FPS[TM]) meets low-standby power and EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. regulations SAN JOSE, Calif. -- Fairchild Semiconductor (NYSE NYSE See: New York Stock Exchange : FCS) introduces the Green FPS e-Series, a new family of Fairchild Power Switch (FPS[TM]) 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 Green FPS products raise power conversion efficiency by 1% and reduce EMI up to 5dB compared to conventional hard-switch converter topologies. These highly integrated FPS devices combine the functionality of a fully avalanche rated SenseFET, a current mode pulse width modulation See PWM. (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). "Fairchild's Green FPS e-Series devices offer designers the advantages of PWM IC and MOSFET (Metal Oxide Semiconductor Field Effect Transistor) The most popular and widely used type of field effect transistor (see FET). MOSFETs are either NMOS (n-channel) or PMOS (p-channel) transistors, which are fabricated as individually packaged integration together with high energy efficiency and reliability in an all-in-one solution, helping them in their never-ending pursuit to meet demanding power consumption and energy regulations affecting today's power supply market," said HK Kim, Fairchild's vice president of the Power Conversion product line. "Utilizing a proprietary valley switching technique, these products provide the highest levels of efficiency to meet the standards as specified by the California Energy Commission The California Energy Commission is California’s primary energy policy and planning agency. Created in 1974 and headquartered in Sacramento, the Commission has responsibility for activities that include forecasting future energy needs, promoting energy efficiency through (CEC (Central Electronic Complex) The set of hardware that defines a mainframe, which includes the CPU(s), memory, channels, controllers and power supplies included in the box. Some CECs, such as IBM's Multiprise 2000 and 3000, include data storage devices as well. ), EU Code of Conduct, and Group for Energy Efficient Appliances (GEEA GEEA Group for Energy Efficient Appliances )." 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. Valley switching operation enables the MOSFET to turn on with minimum drain voltage and offers inherent frequency modulation resulting in a dramatic reduction in EMI noise up to 5 dB compared to conventional hard-switch converters. This valley switching operation also enables these converters to perform soft switching, therefore increasing power conversion efficiency by 1% while drastically reducing heat generation. Designs employing Green FPS e-Series products provide superior system reliability and space benefits compared to discrete MOSFET/controllers, RCC switching converters, or conventional hard-switching solutions due to space saving 8 lead DIP and 8 lead LSOP LSOP Little Shop Of Physics (Colorado State University, Fort Collins, CO) LSOP London School of Pharmacy LSOP Local Services Ordering and Provisioning Committee LSOP Lebanese Society of Periodontology packaging and the inclusion of a variety of protection circuitry. This circuitry includes over-voltage protection (OVP), over-load protection (OLP), abnormal over-current protection (AOCP AOCP Aircraft Out of Commission for Parts AOCP American Osteopathic College of Pathologists AOCP Airborne Operational Computer Program AOCP American Osteopathic College of Proctology ) and thermal shutdown protection (TSD TSD Tay-Sachs disease. ). Additional features include an integrated fixed oscillator oscillator Mechanical or electronic device that produces a back-and-forth periodic motion. A pendulum is a simple mechanical oscillator that swings with a constant amplitude, requiring the addition of energy at each swing only to compensate for the energy lost because of air , under-voltage lock out (UVLO UVLO Undervoltage Lockout UVLO Under Voltage Lock Out ), optimized blanking and gate turn-on/turn-off driver, and temperature compensated precision current sources for loop compensation. 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.
