Infineon Technologies AG has expanded the LITIX Power family with the TLD6098-2ES dual-channel, stand-alone DC-DC controller. These products can also be used as voltage power supplies to meet the growing demand for animation in external LED lighting. And it is said that the controller is the first product that can drive full LED headlights without an additional microcontroller. It also operates four standard LED headlight functions: high beam, low beam, daytime running lights and turn signals.
Each channel of the device provides analog and PWM dimming for precise LED brightness control. Wide input voltage range 4.5V to 60V, even 24V battery system applications can be supported. As a multi-topology controller, it can support boost, buck, SEPIC and flyback topologies. The integrated PMOS gate driver provides high-side load disconnect, dims the LED brightness, and provides adequate system reliability. In addition, the integrated spread spectrum modulator enhances EMC performance, enabling the system to be certified at the customer site.
