MS22T1-C22-4070-VSM-2-00 is a product from STMicroelectronics, a global leader in innovation and semiconductor technology. This device is a high-efficiency, low-cost, single-channel control module for driving AC or DC LEDs.

At its core is a powerful STM32 chip with an ARM Cortex-M4 core, allowing it to be programmed with various function profiles tailored to each user’s needs. In addition, low power consumption and high efficiency make this product widely suitable for LED lighting applications.

Application Field

Thanks to its versatility, this device can be used in a variety of LED lighting applications, such as LED spotlights, LED downlights, LED bulbs, and LED illuminated signs. Furthermore, this module can also be used in streetlights, floodlights, or tunnel lights.

This device is also often used in vehicles due to its small size and the fact that it requires very low power consumption. In addition, it is also suitable for other applications like medical devices, factory automations, and industrial devices.

Working Principle

The device works by using pulse-width modulation (PWM) to accurately control the power delivered to an LED array. By adjusting the PWM frequency and cycling time, the output current of the device can be changed and the light output of the LED’s can be finely tuned. For example, the output can be adjusted to achieve a dimming effect or to control the intensity of the lights. This makes the device highly versatile and suitable for various applications.

In addition, this device supports various modulation schemes such as constant current, constant voltage, and linear dimming mode. This ensures that the output current remains stable and avoid flickering or instability when the device is cycling.

Lastly, the device is also equipped with a temperature sensing function to avoid over-heating. If the temperature reaches a certain threshold, the device will automatically reduce the output current and protect itself from damage.

Conclusion

The MS22T1-C22-4070-VSM-2-00 is a powerful and versatile LED lighting module that is suitable for a wide range of applications. Thanks to STMicroelectronics’ advanced engineering, the device is highly efficient, low-cost and can be programmed to fit almost any LED lighting application.
