On July 4, 2017, Dalian United Holdings, a leading semiconductor component distributor dedicated to the Asia-Pacific market, announced that its product is based on Infineon's Indlon TLD5190QV LED driver for automotive intelligent lighting solutions. . The solution is efficient and low-cost and can control multiple channels of output using one LED Driver.
As people's demand for safe driving continues to increase, they will use low beam, high beam, daytime running lights (DRL), matrix headlights (Matrix) and Pixel lighting systems. All integration into the headlights will be the trend of all automotive smart headlights in the future, and smart headlights have been adopted for advanced models such as Benz, BMW and Audi.

Dalian Dapin has launched the Infineon TLD5190QV LED driver, which is a synchronous H-bridge DC/DC controller with similar functions as the TLD5541-1QV. It has no SPI interface and is especially suitable for LED control electronics without a microcontroller and is easier to implement. In addition, it offers integrated protection, analog and digital (PWM) dimming, and supports adjustable switching frequencies from 200 kHz to 700 kHz. In addition, the TLD5190QV integrates protection functions for over-temperature, over-voltage and no-load conditions, and provides a status output interface for diagnostics of load conditions. It also has a spread-spectrum function to enhance EMI capability.
