Description
The F SB-series is a next-generation, green-mode
Fairchild Power Switch (FPS™) incorporating Fairchild’s
innovative mW Saver™ tech nology, which dramatic ally
reduces stan dby a nd n o-load power c onsumption,
enabling co nformance to al l w orldwide Sta ndby Mo de
efficiency guidelines. It integr ates an advan ced current-
mode pulse width modulator (PWM) and an avalanche-
rugged 7 00V SenseFET in a sing le p ackage, all owing
auxiliary power desi gns with hi gher stan dby e nergy
efficiency, red uced siz e, imp roved re liability, and lo wer
system cost than previous solutions.
Fairchild Se miconductor’s mWSaver™ technolo gy
offers best-in- class mini mum no-load and light-load
power cons umption. An innovative A x-CAP™ method,
one of the five propri etary mWSaver™ techno logies,
minimizes loss es in the EMI filter stage b y eliminating
the X-cap di scharge resistors while sti ll meeti ng
IEC61010-1 safet y req uirement. mW Saver™ Green
Mode gra dually decreases s witching frequ ency as loa d
decreases to minimize switching losses.
A ne w pr oprietary as ynchronous jitter decr eases EMI
emission a nd built-in s ynchronized sl ope compe nsation
allows st able peak-c urrent-mode co ntrol o ver a wide
range of inpu t voltage. T he propriet ary i nternal lin e
compensation ensures constant output po wer limit over
entire universal line voltage range.
Requiring a m inimum n umber of ext ernal c omponents,
the F SB-series provi des a basic platform that is well
suited for the cost-effectiv e flyback conv erter desig n
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

Absolute Maximum Ratings
Stresses e xceeding th e a bsolute m aximum ratings m ay dam age th e device. T he device m ay n ot function or b e
operable above the recomme nded operating conditions and stressing the parts to these levels is not recomme nded.
In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability.
The absolute maximum ratings are stress ratings only.

Notes:
5. All voltage values, except differential voltages, are given with respect to the network ground terminal.
6. Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device.
7. Non-repetitive rating: pulse width is limited by maximum junction temperature.
8. L=51mH, starting TJ=25°C.
9. L=14mH, starting TJ=25°C.
10. Internally limited by Over-Temperature Protection (OTP). Refer to TOTP.
Recommended Operating Conditions
The Recommende d Operatin g Cond itions tabl e defines th e conditi ons for actual device operatio n. Recommen ded
operating conditions are spec ified to ens ure optimal performance to the datasheet specifications. Fairchild does not
recommend exceeding them or designing to Absolute Maximum Ratings.
