LED drivers are used to regulate current through a light emitting diode (LED). By controlling the current, LED drivers are able to target specific lighting requirements and colors. LXC75-1050SW is a DC to DC step up/down power module, specifically designed to drive high-power LEDs in series from a DC supply. It comes with an integrated on/off switch and over temperature protection.

Application Field

With the integration of a universal AC/DC power supply chip, the LXC75-1050SW is the perfect choice for a wide range of applications. It is ideal for applications such as LED lighting, automotive headlamp applications, projector lamps, LCD backlighting, street lighting, and stadium and building lighting control.

Working Principle

The LXC75-1050SW uses pulse-width modulation (PWM) to modulate the LED current. This technology is a basic DC to DC step-up/down converter. It comprises a primary switch mode regulator whose output is rectified by an active rectifier and incorporated into the LXC75-1050SW. It operates by supplying the LED with a consistent voltage to ensure long life of the LED. The PWM voltage in the LXC75-1050SW can be adjusted to the required level by turning a potentiometer. The LXC75-1050SW enables higher current and good efficiency and guarantees high reliability and longevity.

The LXC75-1050SW provides LED current monitoring by means of shunt resistors and a voltage divider, and this facilitates temperature control, thermal shut down and current limiting, enabling very accurate light emission control. The pre-programmed operating parameters, such as over temperature protection level, LED current, can be modified to meet the application requirements. The LXC75-1050SW can also be equipped with an external temperature sensor, making it suitable for temperature sensitive applications.

Advantages

The LXC75-1050SW has a variety of advantages. It features an integrated cooling system for better performance and a longer life cycle. In addition, its output power can be adjusted to the actual requirements of the application, preventing unnecessary power loss. It has high efficiency and low ripple/noise to ensure stable and precise lighting output. The LXC75-1050SW also has a wide range of dimming capability and a high switching frequency, allowing for minimal flickering and low audible noise. Finally, the LXC75-1050SW is compact in size and has a low profile, making it easy to mount and install.

Conclusion

The LXC75-1050SW is the perfect driver for high-power LED lighting applications. Its integrated cooling system, adjustable power output, and wide range of dimming capabilities make it ideal for a wide range of applications.
