PMIC - LED Drivers

LED drivers are power management integrated circuit (PMIC) devices that provide a regulated output current or voltage to a single or multiple LEDs by converting the electrical energy from an unregulated DC input power source. The DLD101-7 is a self-contained, fully integrated LED driver designed for operation with a single supply in industrial and commercial lighting applications.

Operation

The DLD101-7 supports both constant voltage and constant current operation. The constant current mode draws a predetermined amount of current from the input power source across the entire input voltage range. This ensures that the output current to the LED is uniform regardless of variations in input voltage. The constant voltage mode, on the other hand, maintains a steady output voltage level to the LED regardless of input voltage variation.

Features

The DLD101-7 features a programmable input voltage range of 12V to 72V, a wide supply voltage range of 6V to 75V, and a load range of up to 8A. It can operate in both constant current and constant voltage modes. Additionally, the device includes integrated current limiting and over-temperature protection, enabling it to function efficiently and reliably in harsh environments. The device also includes integrated EMC and over-voltage protection, as well as protection against short circuits and open-circuits.

Applications

The DLD101-7 is ideal for a wide range of applications, including industrial and commercial lighting, vehicle lighting, exterior lighting, and computer monitors. The device can be used for both single-color and multiple-color LED applications. Additionally, the device is suitable for use in direct AC-DC conversion and in environments with high torque and current demands.

Working Principle

The DLD101-7 works by receiving an unregulated DC input power source and converting it into a regulated output current or voltage for a single or multiple LEDs. The device is designed to receive and convert the electrical energy from any type of AC or DC input power source. The output current to the LED is adjusted by controlling the voltage across the power supply terminals. The integrated current and temperature protection features ensure reliable and efficient operation even in harsh environments. The device is capable of delivering up to 8A of output power, making it suitable for a wide range of applications.
