AS1116 DB-YELLOW is an advanced evaluation board designed to demonstrate the performance of an 8-channel, constant-current LED driver. The evaluation board features an 8-channel circuit to drive a string of LEDs, allowing for an evaluation of the forward voltage, current, luminous intensity, and total luminous flux of an LED. The evaluation board allows for the characterization of an LED driver chip, allowing it to be used in applications such as color rendering, optics, power conversion, lighting, and many more.

The evaluation board consists of two parts; the main board, and the daughter board. The daughter board is used to connect the LED in the LED driver circuit, while the main board houses all the components associated with the LED driver. The LED driver used on this evaluation board is the AS1116 DB-YELLOW LED driver IC. The AS1116 DB-YELLOW is an 8-channel, high-efficiency constant-current LED driver. It has extended surge protection, a wide input voltage range, and up to 8-channel outputs, with adjustable drive current up to 30mA. The AS1116 DB-YELLOW is housed in a 24-pin, 0.4mm-pitch lead-free package, making it suitable for many application requirements.

Aside from LED lighting applications, the evaluation board can also be used for designing LED driver boards, LED control circuits and LED diagnostics systems. The board is also equipped with interrupt and diagnostic functions, allowing it to be used in applications that require reliable, complex lighting control and sensing. The AS1116 DB-YELLOW evaluation board also features an adjustable brightness switch, allowing for the brightness to be adjusted as desired.

The working principle of the AS1116 DB-YELLOW evaluation board is relatively simple. When a pulse-width-modulated (PWM) signal is applied to the board, the AS1116 DB-YELLOW will convert the signal into an average current and apply this current to the LED. The board is also capable of driving multiple LEDs simultaneously, with each LED being controlled independently. The board also contains a Diagnosis Input pin, which can detect the current, temperature and voltage of the LED, allowing for diagnostics of the LED driver and LED string.

The AS1116 DB-YELLOW evaluation board can be used for a variety of lighting applications, including automotive lighting, outdoor lighting, medical lighting, and many more. The board is capable of driving up to 8 LEDs simultaneously, making it suitable for many applications. The board pays particular attention to high-efficiency and low-noise operation, making it ideal for applications that require a simple, reliable LED driver. In summary, the AS1116 DB-YELLOW evaluation board is an advanced LED driver solution for a variety of lighting applications, capable of efficiently and reliably driving up to 8 LEDs.
