AL3022MTR-G1 is a PMIC – LED driver. It provides the most integrated solution for AC/DC input, PFC with auxiliary boost supply and full driver circuitry. This product is specially designed to meet wide input range (195~435Vac), high efficiency and active power factor correction. Its integrated PFC and boost design is suitable for commercial lighting and other LED lighting applications.

AL3022MTR-G1 is designed to drive up to two independent LED strings with one or two of its available LED channels. Each LED channel utilizes an advanced Digital Blanking Control (DBC) for complete LED dimming control. Its LED current is programmable up to 90mA with low ripple, providing the capability to build a wide variety adjustable LED lighting applications. It also contains an independent analog dimming control circuit, offering a tunable range from 0.1% up to 100% with no additional cost.

The AL3022MTR-G1 also contains on-board over-voltage protection, short-circuit protection, over-temperature protection and over-current protection. The onboard thermal protection circuitry allows the user to set the allowable temperature limit while ensuring protection of the device. The device has a high power factor over 0.90 and will meet the current ENERGY STAR® standards. Additionally, all other LEDs in the strings can be read online through its various analog/ digital/ PWM interfaces.

Overall, AL3022MTR-G1 is a powerful and integrated PMIC – LED driver, and its working principle is simple. It converts AC to DC using the integrated PFC, then it provides the power through one or two channels to the LED strings. Variable LED current allows the LED strings to achieve the desired brightness level, and the LED strings\'s current can be adjusted by the provided analog dimming control circuit. The internal over-voltage, short-circuit, over-temperature and over-current protection circuitry are constantly monitored to ensure the stability of the system and to protect the device from any damages.

The AL3022MTR-G1 is suitable for commercial lighting and other LED lighting applications as it provides high efficiency, active power factor correction and can drive up to two independent LED strings. Its various analog/ digital/ PWM interfaces allow the user to read the LED strings online and its variable LED current of up to 90mA allows the LED strings to be adjustable in brightness. The onboard thermal protection ensures the device is stable and safe. Therefore, the AL3022MTR-G1 is the perfect choice for any PMIC – LED drivers applications.
