LED indication has been used in many applications where an on-off indicator or visual alarm is required. Expensive light sources, on the other hand, require specialized thermal and optical management in order to achieve reliable and long-lasting performance.

Discrete LEDs are typically easier to manage than expensive light sources due to their compact size, greater efficiency and lower system operating temperature. These features allow them to be used in a wide variety of applications, ranging from low-power lighting and general-purpose lighting to industrial and military equipment.

The SMS1105UWDN is a discrete LED indication module designed to provide reliable visual feedback in a variety of operating conditions. At a standard of 45.85V@5A, the LED module is suitable for a wide range of applications, from residential and commercial systems to large scale industrial installations.

The module features a two-stage uni-directional dimming feature with 75% step adjustment that allows for dimming from a peak of 4800k to a minimum of 16,000k for nightime applications.

SMS1105UWDN operates on a half-bridge based DC PWM control, resulting in a direct operating temperature of up to 113 degrees Celsius, making it suitable for a wide variety of thermally challenging applications, including automotive and industrial purposes. The integrated circuit\'s frequency range of between 20 kHz and 50 kHz provides for a flicker free performance, making SMS1105UWDN a versatile and robust choice in an ever-demanding industrial environment.

When compared to other discrete LEDs, the SMS1105UWDN is also energy efficient, consuming less than 1 Watt of power non-stop. The low voltage start-up, made possible through its built-in power management unit, improves the overall efficiency of the system while the 5A current output provides a better performance when compared to its predecessors.

In terms of its working principle, SMS1105UWDN operates on a multi-level synchronous switching process that reduces the amount of switching losses as well as EMI emissions, resulting in higher efficiency. The SMS1105UWDN includes an internal current limit feature, enabling it to maintain a steady current output regardless of the operational conditions. It also features short circuit protection and integration with a wide range of common voltage ranges, making it an ideal choice for a wide variety of applications.

Overall, SMS1105UWDN can be used across a wide range of LED indication applications, from simple light displays for residential and commercial use to complex industrial applications. Its ability to maintain a steady level of current output, regardless of the operating conditions, as well as its energy efficiency and flicker-free performance make it an ideal choice for operations that demand a reliable and sustainable LED indication solution.
