LED drivers are specialized power electronic devices for driving LEDs. They provide the power necessary to operate LED-based lighting solutions across multiple applications and industries. The MLV9C35 is a relatively new driver module for LED lighting applications from Supertex, Inc. It is a highly efficient, isolated LED driver rated for Class 2 operation.

Overview

The MLV9C35 driver is designed to meet Class 2, Level 2 requirements for UL, CSA, IEC, and CE applications. It is rated to provide up to 40W of constant current to power one or two strings of LEDs in series. It has an adjustable voltage range of 4V to 40V and an adjustable current range of 300mA to 2A. The device also has over-voltage, over-current, open/short LED protection features as well as integrated dimming control. This makes it ideal for lighting applications that require precise control of power output.

Working Principle

The MLV9C35 LED driver module uses a type called current-mode control, which is the most common method of LED driver control. This method of driver control works by sensing the current that is passing through the LEDs and controlling the output power by adjusting the total amount of current flowing. This technique helps ensure that a constant current is maintained at a given level, regardless of changes in operating voltage, temperature, or other conditions.

This driver module works by incorporating a current-mode pulse width modulation (PWM) control circuit. This circuit is used to determine the amount of current that will flow through the LEDs, and it is adjusted by changing the width and duration of each PWM cycle. The PWM circuit in the MLV9C35 also includes a dimming control feature which is used to fine-tune the current output and achieve desired lighting levels.

Applications

The MLV9C35 LED driver is suitable for a wide range of power applications such as residential and commercial lighting, architectural, and stage lighting, as well as other specialty lighting. Its high power, Class 2 level of isolation, dimming control, and other features make it an ideal choice for these applications. These features make the MLV9C35 driver an ideal solution for manufacturers looking for a reliable and efficient LED driver for their lighting products.

Conclusion

The MLV9C35 LED driver from Supertex is an excellent choice for a wide range of LED-powered lighting applications. Its efficient current-mode control and comprehensive protection features make it reliable and easy to control. Its adjustable voltage and current range and integrated dimming control allow for highly customizable lighting systems. Manufacturers and installers can use this driver with confidence, knowing that it is rated for Class 2 operation and provides reliable and efficient power for their lighting systems.
