LED Performance

Performance and Pricing Factors for LEDs in General IlluminationWhile CFLs are expected to continue their dominance of the general illumination market for the

foreseeable future, LEDs are continuing to gain in terms of both price and performance

LEDs will exceed 200 lm/W before approaching maturity and a leveling off in efficiency improvements.

What are FSC goals for LED driver?

Essential Technical Trends

* Small PKG & good design rule process

* To increase current output, syn. function could be tied

* Capacitor lifetime decides whole LED board one (capacitor: 6000-8000hr, LED: 25000-30000hr)

* Integrated PFC to increase power factor based on EU regulation (over 3W)* PFC driver is also applicable to flyback solution

* LED drivers for each 350mA, 700mA which MOSFET will be integrated in * High watt LLC solution support integrated MOSFET cover up to over 150W

* Adapted dimming solution for control brightness* Support transducer IC to combine with LED driver as full kits

Thank you
