DLG100PS12 LED Drivers

DLG100PS12 LED Drivers are special electronic components designed to power Light Emitting Diode (LED) devices. A driver is used to regulate the amount of power going to the LED, as it helps the LEDs to perform optimally and enhances their lifetime. Depending on the model, DLG100PS12 drivers offer efficiency, robustness, cost-efficiencies and excellent electrical performance. This enables the end user to cut design cycle time and cost over long-term operations.

Application Field

DLG100PS12 LED Drivers are commonly used in a variety of applications, such as automotive, industrial, medical, signage and display, as well as consumer applications. Automotive applications include lamps, signals, halo color rings and ambient lighting systems. LED Drive are also used for controlling LED fixtures in harsh environmental conditions.

Working Principle

The DLG100PS12 LED Driving Module follows single-stage step-down (buck) architecture. The device accepts an wide input operating voltage range (2.5V to 40V) and require a single external resistor to set the output current in a wide range of 30mA to 70mA. The output current can be further set by a PWM signal at theCT pin.The device employs a fixed frequency current mode control scheme and requires only two external components, a switching MOSFETand an inductor, allowing a compact solution size. A leading-edge blanking function is designed in the DLG100PS12, giving shorter switch off time, and providing good system EMI performance.In addition to safety-related features such as over temperature protection, a soft-start/hiccup current limitation mechanism, the DLG100PS12 also implements programmable valley current modecontrol, that can rapidly reduce the LED current during LED dimming for better system flush current matching.

Conclusion

DLG100PS12 LED Drivers are designed to power a wide variety of LED devices in numerous application fields. By providing wide input voltage range, PWM dimming capability and additional safety features, DLG100PS12 are an excellent choice for designers trying to create efficient and dynamic LED installations.
