Infineon Technologies Automotive Front Light LED Reference Design is a solution for front light high beam/low beams. It uses the flexible multi-topology DC-DC controller TLD5099EP of the LITIX™ Power family in current-controlled buck-boost SEPIC configuration. A single DC-DC channel drives the high beam and low beam. The high beam is activated in conjunction with the low beam or the low beam can be activated alone. This is cost-saving and suitable for entry-level LED headlamps. A PWM dimming feature allows more control of brightness and derating in extreme operating conditions. State-of-the-art diagnosis is provided, and transient robustness.
