PMIC (Power Management Integrated Circuit) - LED Drivers are electronic components that convert electric current from a power source into one or more set voltages that power lights like LEDs. The A6280EESTR-T is a programmable multi-channel integrated circuit which is designed to drive LEDs. It is the perfect solution for powering light sources in a variety of applications due to its features and configurable nature.

The A6280EESTR-T is a 3-channel LED driver with programmable current settings. It is designed to drive up to 20 LEDs in series, each at a maximum current of 1A. It supports PWM dimming with a dimming frequency of 10kHz to 10MHz. The device’s operating voltage range is from 4.5V to 18V, and it is programmed via a two-wire I2C bus. It has a power savings feature that can be used to reduce the current consumption when supplying multiple LEDs with sufficient voltage.

The A6280EESTR-T provides a variety of application fields where it is suitable for use. It is ideal for enabling high-efficiency LED backlighting for LCD displays, ranging from small displays to large-scale video walls. The A6280EESTR-T can also be used for LED strip lighting for accent lighting, architectural lighting, or any other application that requires adjustable LED lighting. It is also suitable for LED lighting in the automotive industry, LED outdoor signage applications, LED tube lighting, domestic lighting, and industrial lighting.

The A6280EESTR-T’s working principle is based on the concept of constant current power supplies. The device is outfitted with three adjustable resistor channels, which can be programmed to deliver a constant current to each LED. The device’s current settings are adjustable from 0.04A to 1A in 0.04A steps. When the A6280EESTR-T is in I2C mode, the user can control the device’s current settings using an external control device. When the device is in PWM control mode, the current settings can be programmed using the same external control device. The A6280EESTR-T is designed to operate at frequencies up to 10MHz, so it is suitable for projects that require high-speed switching of multiple LEDs.

The A6280EESTR-T is an ideal programmable multi-channel LED driver for a variety of applications. Its features allow it to be used in many lighting projects, both indoors and outdoors. With its adjustable current settings and wide range of operating frequencies, it is the perfect LED driver for any LED lighting project.
