Design Considerations

LED lighting designers are challenged with meeting their efficiency and reliability goals faster in advanced lighting designs. TI’s high efficiency conversion topologies are helping designers achieve their goals at a faster rate.

The lack of an output rectifier, in the topology shown, further increases the efficiency of the overall system and an additional benefit of this solution is the simple and robust control. Transient immunity and the current matching characteristic of the multi- transformer topology make it very reliable and the system re-balances automatically in case of an LED failure. Scalability is another key advantage in LED design and the number of LEDs in a string can be scaled up to 16 thus allowing for up-to 64 LEDs per lamp.
