LED lighting can not only improve road driving safety, but also facilitate the realization of flexible styling design, bringing a new design trend, which is becoming more and more important in the automotive field. To meet the ensuing market demands, Infineon Technologies AG has further expanded its LI TIX Power lineup with the introduction of the dual-channel stand-alone DC-DC controller TLD6098-2ES. This controller is the first controller that does not require additional Equipped with a microcontroller,
it can drive a complete car LED headlight by itself. It can realize 4 standard functions of LED headlights: high beam (HB), low beam (LB), daytime running Lights (DRL) and Turn Signal Lights (TURN). In addition, the LITIX Power family of products can also act as a flexible power source to meet the growing demand for animation effects in exterior LED lighting.
The TLD6098-2ES is a multi-topology controller that supports boost, buck, SEPIC and flyback topologies. The integrated PMOS gate driver features high-side load disconnect, which can dim the LED brightness to ensure high system reliability. In addition, the integrated spread spectrum modulator improves EMC performance and facilitates system validation at the customer site. Each channel of the TLD6098-2ES provides analog and PWM dimming for precise control of LED brightness. The TLD6098-2ES has a wide input voltage range of 4.5 V-60 V, and can even support battery system applications with an operating voltage of 24 V.
