AL5809EV1-150

The AL5809EV1-150 evaluation board is part of a family of LED drivers that is used in a variety of applications. It uses a Power MOSFET-diode combination to develop the voltage necessary for the LED array. The LED driver is designed to regulate the current from the input into a constant output current, regardless of the LED’s operating temperature. This constant current is then adapted for driving multiple LEDs at the same time.

The AL5809EV1-150 is capable of driving up to 150 LEDs, with a low ripple and low voltage drop. It is suitable for RGB backlight applications and uses a single-stage power stage to drive the LEDs. The board includes four high power MOSFETs to ensure efficiency, stability and low resistive losses. The MOSFETs are also optimized to provide good thermal performance.

The AL5809EV1-150 evaluation board comes with a comprehensive set of components and instructions to help users get started quickly. It includes four shielded kelvin pumps and two input/output connectors for convenient connections. The board also features an adjustable current/overvoltage limiter, providing protection for delicate LEDs. An ESD protection circuit is included to protect against potential electrical damage.

The AL5809EV1-150’s operating principle is based on pulse code modulation (PCM). This method synchronizes two pulses - one for the current, and one for the voltage - and the result is an output current that is proportional to the input voltage. This technology simplifies the protection circuit, eliminating the need for complex feedback loops.

The AL5809EV1-150 is an efficient and robust LED driver, suitable for a wide range of applications. Its simple, one-stage design makes it easy to integrate into a system, while providing adjustable current and voltage limiting as well as ESD protection. The PCM method of operating further increases its efficiency, minimizing the need for complex feedback loops.

The AL5809EV1-150 evaluation board is a great choice for LED applications, offering a durable and efficient solution. Its small size and low power consumption make it suitable for a variety of devices, and its protective features ensure that your LEDs are always safe.
