Current controlled led driver

LED drivers are widely used for driving high voltage LEDs or lamps or miniature LEDs for indication via microcontroller signals. An LED driver circuit must provide enough current to light up the LED but must limit the current to prevent damage. A constant current regulator is commonly used for high power LEDs. It provides a constant current which will light up the LED . The portfolio of Linear LED Drivers provides Soft-Start Capability, Input Under-Voltage Lockout (UVLO), Output Over-Voltage Protection (OVP), Short-Circuit Detection, and Thermal Shutdown (TSD) Protection features to protect LEDs from extreme voltages and currents.  · The LED driver is a self-contained power supply which has outputs that are matched to the electrical characteristics of the LED (s). This helps avoid thermal runaway as the constant current LED driver compensates for the changes in the forward voltage while delivering a constant current to the LED.

LED drivers are widely used for driving high voltage LEDs or lamps or miniature LEDs for indication via microcontroller signals. An LED driver circuit must provide enough current to light up the LED but must limit the current to prevent damage. A constant current regulator is commonly used for high power LEDs. It provides a constant current which will light up the LED and not damage it. What is a Constant Current LED Driver? Constant current LED drivers are designed for a designated range of output voltages and a fixed output current (mA). LEDs that are rated to operate on a constant current driver require a designated supply of current usually specified in milliamps (mA) or amps (A). Constant current source; LED power supply; An LED driver is an electronic circuit that generates a constant output current from the supply voltage. This controls the LEDs integrated in the lamp. In electrical engineering, this circuit is often referred to as a constant current source. The term LED power supply actually describes a constant voltage source and is used here rather colloquially.
