LED drivers are semiconductor devices that are designed to control the flow of electricity and provide the optimal current and voltage of light emitting diode (LED) lighting products. The LDB-350L series is a family of high efficiency and high reliability, low power consumption step-down constant current LED drivers. This type of driver provides a number of features and benefits that make it ideal for a variety of lighting applications.

Application Field

The LDB-350L series is ideal for a variety of lighting applications ranging from indoor commercial lighting, home, and office lighting to automotive and industrial lighting applications. The driver offers a high performance solution for a wide range of LED applications, and its small form factor, low power consumption and high efficiency make it an attractive solution for space-saving, energy-efficient applications. It can be used in single, double or multiple-channel applications, and its wide dimming control range ensures maximum flexibility for users.

The LDB-350L can also be used for non-lighting applications such as communication, consumer, medical and industrial. It is particularly suitable for battery powered devices that require a simple, low power, efficient and reliable power source. Its integrated input and output overload protection make it well suited for sensitive environments, making it an attractive choice for products in these industries.

Working Principle

The LDB-350L series is based on a step-down [buck] constant current design. The device operates by taking an input voltage, converting it to the appropriate output voltage and current to deliver the desired LED control signal. A set of three integrated power transistors lead to a high efficiency power conversion rate of over 95%.

The driver also has various protection features to prevent overheating or short-circuiting, such as over temperature protection, short circuit protection, under voltage lockup and thermal shutdown. The adjustable output current level ensures that the output of the driver is matched to the specific requirements of the application. These features minimize the chances of system failure, prevent wasted energy, and increase overall product reliability.

The LDB-350L is an ideal choice for applications where high efficiency, high power density and reliability are required. Its versatile design allows for a variety of input and output settings, offering maximum design flexibility for applications in a wide range of industries.
