What are the characteristics of a high power LED driver for use in an automotive environment?

Wide input current and LED current voltage range, wide output voltage, high conversion, strict regulation, low noise, constant frequency operation, independent light control, wide dimming ratio range, compact footprint and few external components. Even with the above performance characteristics, the LED driven by the LED driver must also be able to provide the required optical output from the lowest possible power level (Liu Ming),.

For high power LED drivers, which are to be used in the automotive environment, some of the features are necessary. Obviously, it must be able to use a topology that simultaneously satisfies the input voltage range as well as the desired output voltage and current requirements to provide sufficient current and voltage for different types of LED configurations.

However, they should also have the following characteristics: wide input current and LED current voltage range, wide output voltage, high conversion, strict regulation, low noise, constant frequency operation, independent light control, wide dimming ratio range, compact footprint and few external components.

Even in the case of the above characteristics, driven by LED LED must also be able to provide the required amount of light output from the power level as low as possible (Liu Ming), and does not lead to suffer significant restrictions of thermal design.

Fortunately, for the headlight designers, they had both high LED and high performance LED drive, which can realize in the past has been considered the mutex (i.e., from the low input power level to provide high light output).
