A6211GLJTR-T, a PMIC - LED Drivers, is a precision current regulator for driving high-current LEDs up to 5A. It is designed to drive up to 2 strings of 1-5 LEDs in series, protected by loop current limit and thermal shutdown protection. The wide average current range makes it suitable for recently upgraded high brightness and high quality lighting demand.

The performance of A6211GLJTR-T is especially designed for LED lighting applications and provides a high level of integration and accuracy. The system-level protection and performance functions provide improved operation, reliability, and cost savings compared to traditional LED driver designs. Its operation is fully integrated with current, voltage, and temperature monitoring.

The A6211GLJTR-T features a wide output voltage range of 5.4V to 24V, adjustable current limit of 100mA to 5A, adjustable LED current of 350 mA to 1A, power on reset, and built-in soft start. Its high efficiency and low dropout voltage are essential for LED lighting applications, providing a more stable light output and longer life for your LED lights.

When the input voltage exceeds the kVoltage level, the device outputs the minimum voltage to protect the LED from high voltage damage. And its open LED protection prevents an LED string from continuing to operate if one LED is disconnected, ensuring normal operation of the LED lighting system. In addition, the A6211GLJTR-T also provides thermal protection to protect the LED driver and LED string. The LED driver temperature is monitored and if the temperature reaches a pre-set limit, the A6211GLJTR-T will reduce the output current to prevent over temperature damage.

The A6211GLJTR-T also incorporates several advanced system level protection and performance functions. It has a built-in digital loop current limit, adjustable fault shutdown level and short circuit protection, enabling it to monitor and regulate the average current of a series of LEDs. In addition, the A6211GLJTR-T also features adjustable leading edge dimming (LED) to dim the LED output. This is done by controlling the peak of the dimming output waveform, which can be set to provide a more consistent light output.

The A6211GLJTR-T is an ideal choice for driving a wide range of LED lighting applications. It has a wide output voltage range, adjustable current limit and adjustable LED current, making it suitable for a variety of applications, including street lights, pathway lighting, residential and commercial lighting. Its advanced system protection functions reduced the stress on the LED and the power supply, improving life, efficiency and system reliability.
