The A6279ELPTR-T is a high efficiency, low power consumption, Dual Output LED Driver from Analogictech which is regulated for constant brightness. This device is classified as a PMIC – LED driver, and is ideal for use with both commercial and industrial lighting designs. The A6279ELPTR-T combines both a high-sensitivity integrated voltage control and a constant-current source to accurately regulate the brightness of two independent LED strings.

The A6279ELPTR-T is designed to be used in conjunction with constant current sources and power supplies. This device can also be used to control both AC and DC LED systems as well as buck and boost configurations. The driver offers a wide range of dimming options, allowing it to accurately regulate the brightness of both an AC and DC, while also offering the ability to set a minimum current level and a maximum current level. Additionally, the device supports pulsed width modulation (PWM) dimming and operates with a wide voltage range from 3.3V to 24V.

In terms of its application field, the A6279ELPTR-T is ideally suited for applications where accuracy and low power consumption are required such as automotive, medical, and architectural lighting. This device is also perfect for a range of lighting applications, including spot, accent, fog, and down lighting as well as task lighting. The A6279ELPTR-T is capable of operating with a wide input voltage range from 3.3V to 24V and is equipped with a slew rate protection and adjustable over-voltage current limit circuit.

In terms of its working principle, the A6279ELPTR-T can be used to control two LED strings, referred to as String A and String B. Each string is connected to the driver’s input voltage, and the A6279ELPTR-T’s output is connected to both of the strings. When the input voltage rises, the driver increases the output current to keep the brightness of the strings at the desired level. The device’s sensing circuitry ensures that the output current is accurately regulated even at extreme temperatures. Additionally, the driver’s integrated current-sensing circuit allows for precise control of the output current and continuous monitoring of the total input current.

The A6279ELPTR-T is an excellent device for applications requiring accuracy, low power consumption and the capacity to control both AC and DC LEDs. Its wide input voltage range, current sensing circuit and efficient, low-power regulation make it suitable for a variety of commercial and industrial lighting designs. Furthermore, the device’s adjustable over-voltage current limit circuit and slew rate protection provide further protection and increase the durability of the driver over a wide range of temperatures and configurations. All of these features make the device a great choice for intelligent LED lighting designs.
