Infineon Technologies LITIX™ Basic Automotive LED Drivers

Infineon LITIX™ Basic Automotive LED Drivers are optimized for the control of low to medium power LEDs in automotive applications. The whole family of linear constant current sources offers footprint compatibility ranging from 1 to 3 output channels with typ. 60-180mA and enables stable and reliable LED brightness by precise current control. The integration of features also increases the system reliability by component reduction on board level, ensures system protection (e.g. against ISO pulses) and can help to optimize system efficiency. In addition the automotive optimized scalable feature set of the Infineon LITIX™ Basic Automotive LED Drivers simplifies lighting system solutions by integrating protection and diagnostic features. They also enable the reuse of core design to reduce development effort and time.
