PMIC - LED Drivers broadly refer to application modules for power management, integrating multiple mixed voltage regulators, general-purpose power converter solutions and control circuitry, as well as supporting integrated solutions for driving multiple LEDs. The MSL3085BT-R is a smart high speed power module specifically designed to drive multiple LEDs, and it is a fully-featured and highly efficient constant current sink that eliminates the need for external components. It is suitable for a wide range of LED applications in the industrial, automotive, consumer, and telecommunication fields.

Application Field
MSL3085BT-R is ideal for driving single and multiple LED configurations, as well as driving LEDs in high-temperature and high-power consumption applications. LED lighting applications such as LED street lights, LED interior lighting, LED signage, LED control light, LED spotlights, LED display backlighting are some of the most common applications where it can be used. Automotive applications such as infotainment, lighting, battery powered driving, and security system applications can also utilize the device’s features.

Working Principle
The MSL3085BT-R operates on a simple linear mode load regulation topology to achieve a constant output current. It consists of a programmable current sink that regulates the output current of the LED by controlling the current mirror circuit. A variable voltage is supplied to the LED string. Depending on the LED voltage and the current sink voltage, the LED current will be regulated. It also incorporates integrated switches to allow the use of isolated LED string topologies.

The device is capable of driving up to four separate LED strings. A unique feature of the MSL3085BT-R is that it is able to deliver up to 2A of current with a high peak current transient response. The high-efficiency switch mode controller ensures clean power delivery, minimizing EMI. The device also supports a wide range of 4.5V to 27V inputs to enable compatibility with most standard power supplies.

The device features a wide range of protections, including open-circuit, over-current, and over-temperature protection. It also has a programmable frequency range of 500kHz to 1.2MHz, which allows for quick response to changing load conditions. Additionally, it also features frequency fold-back, which reduces the switching frequency during low-care load conditions, thereby reducing acoustic noise.

The MSL3085BT-R provides powerful and efficient control of LEDs, with a wide range of integrated features and protection parameters. The device is robust and reliable, and is ideally suited for lighting applications in residential, commercial and industrial spaces. It offers the highest level of performance and flexibility, making it a great choice for LED drivers.
