Green
FPS™ e-Series™ 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).
Features and Benefits
Improved reliability due to internal
protection including over-voltage
protection (OVP), over-load protection
(OLP), abnormal over-current protection
(AOCP) and thermal shutdown protection
(TSD).
Reduces EMI through variable frequency
control and inherent frequency modulatio1
High efficiency through minimum
voltage switching and advanced burst
mode operation for stand-by mode
to reduce power consumption
Narrow frequency variation range
over wide load and input voltage
variation
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 and fault protection
circuitry.
