The AS1116-QF_DK_ST B evaluation board is a LED driver board with a wide range of applications. It is a cost-effective solution for constructing high quality LED systems. The board is specifically designed to drive 6 to 8 strings of white LEDs at regulated current levels. It also supports a spread spectrum technique that decreases EMI emissions while allowing the LEDs to be operated at their maximum efficiency.

The AS1116-QF_DK_ST B evaluation board features an intelligent and compact controller that can be used for programming the desired brightness and current levels for each string of LEDs. Through this board’s programmable serial interface, the user can easily configure the board’s settings, with parameters from digital dimming, timing, and temperature compensation dimming features. The built-in real time clock allows for accurate timing of the events, such as scheduled dimming and switching of different channels.

The AS1116-QF_DK_ST B board also has multi-channel, secondary LEDs that can be programmed to light up in sequence along with the primary LEDs. This allows for dimming the secondary channels independently. It also offers separate channels for powering LEDs that require a different drive current than the primary LEDs. This helps to reduce the complexity of the system wiring, thus reducing system cost.

The AS1116-QF_DK_ST B is extremely easy to use and set-up. It has a built-in oscillation detector that measures the ripple present on LEDs which helps to set the right current level for optimal performance. It also has integrated active-to-sleep tracking drivers for dimming the LEDs, which helps to reduce the power consumption. The board also features a smart over temperature monitoring system that increases the operating temperature if required.

At the core of the AS1116-QF_DK_ST B is a powerful, low-cost and flexible field-programmable gate array, which allows for implementing custom logic or functions. It features various communication options based on RS-485, I2C, which makes it suitable for networking with other devices. Moreover, the board has a wide selection of available timers, counters, and analog inputs that facilitate a wide range of applications.

To sum up, the AS1116-QF_DK_ST B is a highly advanced, cost-effective LED driver board with great potentials. It is efficiently designed to drive 6 to 8 strings of white LEDs with regulated current levels and offers real-time clock and temperature compensation dimming features. Its multi-channel and programmable serial capability allows users to easily configure the board settings and to reduce system wiring cost. Furthermore, its powerful FPGA provides hooks for implementing custom logic and functions. All these features make the AS1116-QF_DK_ST B one of the best options for a high quality LED system.
