Overview:

LED lifetime is strongly influenced by increased operating temperature, therefore thermal considerations need to be taken into account. This webcast describes a straightforward implementation of a thermal foldback technique for a linear constant current LED driver using low cost NTC sensing resistor.

You will learn:

• The effects of temperature on an LED circuit
• What is thermal foldback
• How to protect an LED and how to design circuitry providing thermal foldback functionality
