It is ideally suited for applications that require robust operation, as the board can maintain accuracy and performance at all times.

Working Principle

The AP1694AEV11 evaluation board is based on the principle of constant current source of LED drivers. It employs advanced current-mode PWM control, which enables it to achieve a high degree of flexibility and reliability. This control technique allows the user to adjust the current setting according to the requirements of the application. The board also has a multiple channel output support that allows the user to control multiple LED strings at once. It also offers a short circuit protection feature that prevents output current from exceeding the maximum rated value.

The integrated active peak current control circuit is another feature of the AP1694AEV11 that offers improved system performance. This circuit works by limiting the peak current of the LEDs, ensuring that the lifespan and brightness of the LEDs is not degraded by exposure to excessive current. The active peak current control feature also allows the user to configure the peak current value according to their specific application needs.

The AP1694AEV11 also includes an intelligent dimming control algorithm that optimizes the power dissipation and allows for smooth dimming of LED sources. This feature helps in increasing the lifespan of the LED and improving the overall brightness of the LED. The board also offers integrated short circuit, thermal shutdown, and thermal protection features that allow it to protect itself against over-current, over-temperature, and other potential damage.
