Application Field & Working Principle

The A8519KLPTR-T-1 has a wide range of applications in outdoor lighting applications, such as street lights and pathway lighting. It is designed to drive LEDs with a wide voltage range from 4.5V to 14V, making it ideal for these applications. The A8519KLPTR-T-1 uses switch mode power conversion technology to efficiently convert the input voltage to a regulated output current for driving the LEDs.

The internal switch-mode power conversion architecture of the A8519KLPTR-T-1 achieves high accuracy current regulation and excellent efficiency. The device provides an accurate current control to ensure a constant output current, even under varying line and load conditions. Additionally, the A8519KLPTR-T-1 employs an advanced protection loop circuitry to protect against overvoltage, overcurrent, overtemperature, and overvoltage conditions.

The A8519KLPTR-T-1 features an internal soft-start circuit that limits inrush current during turn-on and keeps the input voltage within limits to prevent overvoltage conditions and damage to the LED circuit. Additionally, the A8519KLPTR-T-1 also incorporates an internal active voltage clamp, which limits the output voltage and prevents damage to the LED. The A8519KLPTR-T-1 also includes an internal undervoltage lockout (UVLO) circuit which prevents the device from operation when the input voltage is below a preset level.

The A8519KLPTR-T-1 features a power-on reset circuit and an adjustable soft-stop circuit that limits the output current during shutdown. The device also features an adjustable overcurrent protection circuitry that limits the output current to the specified level, preventing destructive currents from occurring in the LED circuit. Additionally, the A8519KLPTR-T-1 includes an adjustable overtemperature protection circuitry that limits the output current to the specified level, preventing damage to the LED from excessive temperatures.

The A8519KLPTR-T-1 is an ideal LED driver for outdoor lighting applications due to its wide input voltage range, high accuracy current regulation and excellent efficiency. The device provides a complete solution for driving LEDs in outdoor lighting applications, allowing for an efficient and reliable system implementation.
