INFINEON LITIX TLD6098-2ES dual-channel, stand-alone dc-dc controller can drive a full LED headlamp by itself without an additional microcontroller. Device can also operate the four standard LED front light functions: High Beam (HB), Low Beam (LB), Daytime Running Lights (DRL) and Turn Signal (TURN). Product can also be used as a voltage supply to meet the growing demand for animation in exterior LED lighting. As a multi-topology controller, device enables boost, buck, SEPIC and flyback topologies. The integrated PMOS gate drivers provide high-side load disconnection to dim the LED brightness and to ensure adequate system reliability.
