LED Drivers

LED drivers provide a vital role in the functioning of LEDs, as they control the voltage and current those LEDs receive. While the most energy-efficient solution is to use a constant current driver, applied voltage drivers are still widely used in many applications. One such driver is the EBR020U-0720-28, which offers isolated AC-DC or DC-DC power conversion.

EBR020U-0720-28 Application Field and Working Principle

The EBR020U-0720-28 is a wide-range isolated LED driver and DC-DC converter. It offers adjustable power output and operates on an input range of 200 volts AC to 500 volts AC to output a constant voltage of 28 volts DC. The driver is suitable for use in most LED lighting applications, especially when a constant voltage power supply is needed for more than one LED. Its adjustable output control can also be used to reduce energy consumption and maximize performance.

The EBR020U-0720-28 features a PFC (Power Factor Correction) function to increase the efficiency of power conversion. The driver is equipped with constant current limiting, a temperature control circuit, and overvoltage/undervoltage protection to guarantee safe operation and long life. The driver also has a built-in EMI filter to reduce interference from electronic devices.

The EBR020U-0720-28 is equipped with a double topology design which allows the user to select either a buck or boost mode. In buck mode, the input voltage is controlled to be lower than the output voltage, while in boost mode the input voltage is controlled to be higher than the output voltage. The output voltage is selected according to the input voltage, and the output current is controlled according to the output voltage setting.

The EBR020U-0720-28 provides a very efficient solution for lighting applications. Its adjustable output current control allows users to match the output current to their LED load for maximum energy efficiency and long LED life. The convenient buck-boost mode enables the user to choose between two different topologies depending on the application, and the built-in protections ensure safety and longevity.
