SSL5031BDB1207UL Evaluation Boards - LED Drivers Application Field and Working Principle

The SSL5031BDB1207UL LED evaluation board is a single-channel LED driver designed for use with Cree LED optical boards. This LED driver board is designed to deliver superior efficiency, accurate power control and dynamic current compensation in single channel configurations. This LED driver is optimized for Cree LED modules and can be used with a wide range of Cree LED modules.

The SSL5031BDB1207UL LED driver offers the latest in performance and flexibility. The high operating efficiency and wide input voltage range allows the SSL5031BDB1207UL to run easily in extreme environmental conditions. The board uses advanced digital control theory and a patented current steering algorithm to ensure precise current control. This ensures smooth dimming control, no flicker and precise output current control.

Application Field

The SSL5031BDB1207UL is suitable for applications where efficient and reliable lumens output are needed. It can be used for applications such as spot lighting, task lighting, flood lighting, architectural lighting and lighting for general illumination. This LED driver board is also suitable for applications in both indoor and outdoor displays, as well as automotive, aircraft, and industrial environments.

Working Principle

The SSL5031BDB1207UL LED driver operates by using Pulsed Power Supply (PPS) technology, which is based on the principles of Pulse Width Modulation (PWM) and pulse density modulation (PDM). PPS can be used to drive LEDs at either low-level or high-level current. In low-level currents, the LEDs are driven with a series of short pulses that are triggered by a short control signal. The current level of the LED is determined by measuring the total number of pulses per second. In high-level currents, the LEDs are driven with a continuous pulse, and the current level is set by adjusting the pulse width.

The SSL5031BDB1207UL offers advanced current programming technology that allows for precise current adjustment and smooth dimming control. The board also offers the latest in safety and protection, with input overvoltage protection and output over-current, over-voltage and over-temperature protection. The patented current steering algorithm allows for precise current control, preventing flicker and providing superior performance.

The SSL5031BDB1207UL evaluation board is designed for easy use, with screw terminal connections for plug-and-play setup. Its advanced design ensures high performance, precision, and durability. This LED driver is ideal for applications where efficiency, reliability, and superior brightness are needed.
