LITIX™ - Automotive LED Driver IC
Tailor-made LED driver ICs for automotive lighting ICs applications.
LITIX™ - Automotive LED Driver IC subcategories
LITIX™ is the best solution to benefit from the advantages of LEDs providing full protection to your lighting application in automotive, e.g. for LED Front Lighting or LED Rear Lighting. A constant current regulation is the enabler for stable brightness over the whole automotive temperature and voltage range. LITIX™ will protect itself and the LED against overstress caused by e.g. voltage spikes or overtemperature. Some members of the LITIX™ Family provide diagnostic functionality of open and shorted LED as well. All these features are required to drive LEDs inside a car with harsh automotive conditions.
LITIX™ Automotive LED driver from Infineon consists of five sub-families:
- LITIX™ Basic is a flexible linear current source family with scalable feature set
- LITIX™ Basic+ is an extension of existing LITIX™ Basic with additional features, e.g. the most flexible Single LED Short in the market
- LITIX™ Linear provide linear current sources for low, medium and low-cost high-power applications
- LITIX™ Power products are suited for DC-DC converter and controller for medium to high-power applications
- LITIX™ Power Flex products are suited for multitopology DC-DC controller for highest flexibility/ power applications
Infineon Technologies is supporting the LED rear light success story with several generations of LED drivers: LITIX™ Linear, LITIX™ Basic and LITIX™ Basic+. To find your suitable product for your LED front lighting solution, discover Infineon´s LITIX™ Power and LITIX™ Power Flex families.
Infineon offers a reference design for high beam and low beam combination, using the TLD5099EP. This Infineon Reference Design Guide describes a detailed implementation of an automotive frontlight high beam / low beam combination using the flexible multitopoly DC-DC controller TLD5099EP of the LITIX™ Power family in current controlled buck-boost SEPIC configuration.
Infineon automotive-optimized LED drivers address interior and exterior, low-power to high-power automotive LED applications such as: high and low beam, fog, DRL, position, tail, stop, CHMSL, RCL, reverse, turn indicator, dome, ambient lighting, status lamps etc.
For resistor-based LED taillight designs the SPIDER+ LED family offers cost-optimized LED control either on a central BCM or on decentralized electronics. The included diagnostic and protection functions enable the use of the smallest possible wire diameter
It also includes an integrated pulse width modulator to easily implement a dimming function with reduced color shifting and a spread spectrum modulator to improve the EMI performance. It is designed to support fixed current and fixed voltage configurations in multiple topologies such as Boost, Buck, Buck-Boost, SEPIC and Flyback by simply adjusting the external components. The TLD5099EP drives a low side n-channel power MOSFET from an internal 5 V linear regulator.

The H-Bridge architecture is among the most efficient buck-boost topology for high current applications. The device can work in current mode (E.G. LED driver, battery charger) or as a voltage regulator. Capable to drive multiple LED functions (E.G. LB, HB, DRL) with a single DC-DC converter for a more compact and efficient design.
