Expanded family for full LED headlamps without a microcontroller

Infineon Technologies AG has expanded the LITIX Power family with the dual-channel, stand-alone DC-DC controller TLD6098-2ES. The controller is claimed to be the first product that can drive a full LED headlamp by itself with no additional microcontroller. It can also operate the four standard LED front light functions: High Beam, Low Beam, Daytime Running Lights and Turn Signal. Also, these products can be employed as a voltage supply to satisfy the increasing demand for animation in exterior LED lighting.

As a multi-topology controller, it facilitates boost, buck, SEPIC and flyback topologies. The integrated PMOS gate drivers deliver high-side load disconnection to dim the LED brightness and to provide adequate system reliability. Also, an integrated spread spectrum modulator enhances the EMC performance to enable the system qualification at the customer site. Each channel of the device provides both analog and PWM dimming for precise LED brightness control. With the wide input voltage range of 4.5V to 60V, even 24V battery system applications can be supported.
