LED Driver Solutions for Indian Market

Helping You Solve Your Lighting DesignChallenges

The LED Reference Design Cookbook isdesigned to provide you with a valuable tool tohe lp you so lve your l igh t ing des ignneeds.Customers seeking the latest in innovativeand affordable LED lighting solutions can benefitfrom TIs broad product portfolio of AC/DC,DC/DC, LED drivers, power managementdevices, wireless and wired interface control andembedded processors.

Designers have the option of not only controllingthe power stage, but regulating LED currents aswell, eliminating the need for multiplecomponents and reducing system cost. Systemscan be designed to accurately control voltageand current regulation for precise light intensityand color mixing, temperature monitoring toprevent thermal runaway, intelligent/adaptived i m m i n g , a n d f a u l t d e t e c t i o n ( o v e rvoltage/current, blown string). Communicationwith external systems is also possible viapowerline communication (PLC), wirelesstechnology or interfaces.

LED lighting designers are challenged withmeeting their efficiency and reliability goals fasterin advanced lighting designs. Tis lightingportfolio is helping designers achieve their goalsat a faster rate.

High-Light Output Drivers PFC + Buck + Multiple StringsSIMPLEDrive: PFC + DC-DC + Multiple Buck stages

Benefits One control section for all string currents, Lower part count, higher reliability and lower cost

PFC Stage -> Required in any implementationLow Side Buck -> Provides constant LED Current and main controlSeries Transformers -> Provides constant current to each LED string

Drawback All strings will be dimmed simultaneously

(if individual dimming is required)
