Fairchild Semiconductor's Green FPS(TM) e-Series(TM) Optimizes Power Efficiency and System Reliability in Flyback Power Supply D

Fairchild Semiconductor (NYSE: FCS) introduces 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 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.
