AP1695EV4

The AP1695EV4 is a LED driver from the Evaluation Boards - LED Drivers family. Its primary purpose is to allow designers to quickly evaluate and test various LED configurations for driving, displaying, and controlling. The AP1695EV4 runs in the host-side of a system, where it works in conjunction with an LED driver IC to create an LED system with desired brightness and lighting effects. It accomplishes this by taking the LED current sinking and voltage sourcing signals from an LED driver IC, and then provides the necessary controls and interfaces to configure a LED channel.

The AP1695EV4 offers a variety of features that make it ideal for LED testing. The application can easily bridge the gap between the receive and transmit terminals of the LED driver IC, so that the LED channel can be directly tested and simulated in the application itself. The application provides adjustable LED current and voltage settings, along with a range of adjustable timer settings for controlling the LED light output from 0.1ms to 64ms, in an effort to simulate various LED dimming effects with specific dimming profiles. In addition, the LED driving and brightness parameters can also be manually tweaked, such that the LED light output can be adjusted to achieve an optimum user desired light brightness.

Aside from configuring and controlling the LED channels, the AP1695EV4 is also designed to be able to monitor and measure the performance of the LED system. As part of the application, it has a built-in power measurement system which is capable of monitoring the power consumption of the entire LED system, along with a voltage and current sensor for monitoring the performance of each LED channel. This allows designers to quickly evaluate the current and voltage performance of their LED solutions, as well as provide a comprehensive lead time and power output estimation of the entire LED system.

In conclusion, the AP1695EV4 evaluation board is an ideal solution for both testing and operating LED systems. It provides the necessary interface and controls to quickly configure and monitor a LED system, in an effort to determine the most viable LED channel configuration. Additionally, it has a built-in power measurement system and voltage/current meter, which provide designers with detailed insights into their LED performance and power consumption. Therefore, the AP1695EV4 is an ideal tool for testing and simulating various LED solutions for a wide range of applications.
