Infineon Technologies LITIX™ Power Automotive LED Driver ICs

Infineon Technologies LITIX™ Power Automotive LED Driver ICs are ideal for design-driven frontlight functions like day-time-running lights (DRL). LEDs are becoming more common in cars, with basic LED headlamps as an option. Those LED solutions use several discrete LEDs in one chain with string voltages of up to 60V or less. LEDs with a high forward current of even 3A or more are also used. Both implementations require DC/DC solutions and either boost, buck, or buck-boost architectures. The LITIX Power family consists of DC/DC devices which are perfectly fulfilling these requirements.
