EA EVALEDIP320B Evaluation and Demonstration Boards and Kits Application Field and Working Principle

The EA EVALEDIP320B is an evaluation board and demonstration kit designed to explore and enable further development for versatile LED lighting applications. The board comes with all necessary functional components for a constant current LED driver, allowing the user to connect up to ten LEDs for various LED demonstration applications. It adopts a dual-chip solution featuring P2803 (control logic) and P7813 (gate driver) for the latest LED driver evaluation.

The LED board provides adjustable control to allow users to select the LED forward voltage and the total input power up to 350mA. With its adjustable output control, it can achieve dimming level control via a PWM signal. Furthermore, the board features a test port that supports up to 30V input for testing the driving function of various LED modules. This evaluation kit serves as an ideal tool to develop dedicated lighting applications such as lighting dimmer, LED dimmer switch, LED driver prototype, LED light strip driver, and more.

General Application

The EA EVALEDIP320B is designed to be used as an evaluation board and demonstration kit for LED lighting applications. It is ideal for LED lighting projects, such as lighting dimmers, LED dimmer switches, LED driver prototype, LED light strip drivers, and more.

Operating Principle

The EA EVALEDIP320B LED evaluation board features two chips: P2803 (control logic) and P7813 (gate driver).
