Product Table
Increasingly, LED lighting solutions are used in the front
area of the car, especially in the Premium segment.
LED Frontlight solutions are usually implemented using
several discrete LEDs in one chain which leads to a string
voltage of up to 60V or using less LEDs with high forward
current up to 1.5A. Both implementations are requiring
DC/DC solutions either boost, buck or buck-boost
architectures are needed. The Infineon® Power LED Driver
Family consists of DC/DC devices which are perfectly
fulfilling these requirements.
