Description
The FSB-series is a next-generation, green-mode
Fairchild Power Switch (FPS™) incorporating Fairchild’s
innovative mWSaver™ technology, which dramatically
reduces standby and no-load power consumption,
enabling conformance to all worldwide Standby Mode
efficiency guidelines. It integrates an advanced current-
mode pulse width modulator (PWM) and an avalanche-
rugged 700 V SenseFET in a single package, allowing
auxiliary power designs with higher standby energy
efficiency, reduced size, improved reliability, and lower
system cost than previous solutions.
Fairchild Semiconductor’s mWSaver™ technology
offers best-in-class minimum no-load and light-load
power consumption. An innovative AX-CAP™ method,
one of the five proprietary mWSaver™ technologies,
minimizes losses in the EMI filter stage by eliminating
the X-cap discharge resistors while still meeting
IEC61010-1 safety requirement. mWSaver™ Green
Mode gradually decreases switching frequency as load
decreases to minimize switching losses.
A new proprietary asynchronous jitter decreases EMI
emission and built-in synchronized slope compensation
allows stable peak-current-mode control over a wide
range of input voltage. The proprietary internal line
compensation ensures constant output power limit over
entire universal line voltage range.
Requiring a minimum number of external components,
the FSB-series provides a basic platform that is well
suited for the cost-effective flyback converter design
with low standby power consumption.
Applications
General-purpose switched-mode power supplies and
flyback power converters, including:
 Auxiliary Power Supply for PC, Server, LCD TV,
and Game Console
 SMPS for VCR, SVR, STB, DVD, and DVCD
Player, Printer, Facsimile, and Scanner
 General Adapter
 LCD Monitor Power / Open-Frame SMPS
