Light emitting diode (LED) drivers are an important aspect of lighting system design. All lighting applications require an efficient and robust power conversion solution to improve system performance and reliability. In order to meet the various requirements of lighting applications, AS1106PL_DK_SB evaluation boards are designed to provide a purpose-built platform for evaluation and testing of LED drivers.

AS1106PL_DK_SB is a kind of LED driver evaluation board which uses the AS1106PL three-channel LED driver IC from Taiwan Semiconductor. This evaluation board is designed to evaluate and analyse the LED driver’s system performance and its LED lighting control capability. It has an integrated PWM dimming function, allowing users to adjust the brightness of each LED channel.

The AS1106PL_DK_SB evaluation board can be used in various LED lighting applications such as backlight applications for LCD display, traffic signs, indicating lights and more. These applications demand precise control of the LED light intensity and lighting effects. The AS1106PL_DK_SB evaluation board may be used to test the LED driver’s system performance and LED lighting control capabilities.

The working principles of the AS1106PL_DK_SB evaluation board are based on the AS1106PL three-channel LED driver IC. The driver uses a linear high-side group current regulation and is comprised of three separate identical channels, which can be independently controlled via external PWM signal. The driver features an adjustable output current per channel and allows each channel to be connected to three separate LEDs in series.

At the same time, the AS1106PL also supports On/Off control, allowing the user to control the status of each LED channel independently. When the PWM signal is increased, the channel current increases, thus the LED channel brightness increases. Conversely, when the PWM signal is decreased, the channel current decreases, resulting in decreased LED brightness.

The AS1106PL_DK_SB evaluation board can also be used to analyze the power efficiency of the LED driver, by measuring the efficiency of the driver at different output levels and under different conditions. The AS1106PL_DK_SB also supports auto power saving mode, which enables the evaluation board and LED channels to self-adjust their current consumption depending on the light intensity, in order to reduce power consumption.

In addition, the AS1106PL_DK_SB evaluation board can support DC/DC power conversion for LED power supply, allowing the voltage input range to flexibly match that of the LED’s power supply range. This feature provides flexibility for LED lighting design and reduces design complexity.

The AS1106PL_DK_SB evaluation board is a reliable and easy-to-use platform for LED lighting design. It is designed with features to compare different LED control solutions and analyze various LED lighting effects. This evaluation board is a great development tool, which can help designers to effectively evaluate, analyse and verify their LED driver design.
