Press Release Summary:
Based on valley switching technique, Green FPS e-Series power switches combine functionality of fully avalanche rated SenseFET, PWM IC, and various protection functions. Using burst mode operation, they reduce standby power consumption to below 0.2 W at no load conditions (below 1 W at 0.5 W load) and meet stand-by power regulations. Units are suited for for DVD players, set top boxes, LCD monitors, and other 25 W and lower power supply designs.

Fairchild Introduces Green FPSTM e-Series(TM) for Flyback Power Supplies
SAN JOSE, Calif. - May 22, 2007-Fairchild Semiconductor (NYSE: 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 (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 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 (CEC), EU Code of Conduct, and Group for Energy Efficient Appliances (GEEA)."
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 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) and thermal shutdown protection (TSD). Additional features include an integrated fixed oscillator, under-voltage lock out (UVLO), 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.
