The LM3404MR/NOPB is a member of the PMIC - LED Drivers category of integrated circuits. It is a high-current regulator designed to drive high-power LEDs, with a maximum current of 1.2 A. The LM3404MR/NOPB is a high-efficiency device that also incorporates over-voltage and over-temperature protection, making it well-suited for use in LED lighting applications such as automotive and architectural LED backlighting, LED message boards, LED signage, LED source lights, LED replacement lamps, and LED downlights.

LED lighting products are constantly increasing in popularity. This has led to a surge in demand for efficient and reliable LED drivers, such as the LM3404MR/NOPB. By being able to handle a larger current than other drivers, the LM3404MR/NOPB gives designers the ability to drive more LEDs with a single driver. It also provides protection for each LED to ensure a longer lifespan, making it an invaluable tool for designers of LED lighting systems.

The LM3404MR/NOPB is essentially an adjustable constant current regulator. It is designed to deliver a regulated current to the LEDs it is driving, based on the external resistor connected to the REF pin. The regulator is controlled by the Input Voltage, which is applied to the EN pin. This allows the regulator to be easily configured for a wide range of input voltages, from 4.8V – 55V.

The LM3404MR/NOPB also provides a number of features to protect the LED driver, and the LEDs it is driving. The device contains a VCC OVP (Over-Voltage Protection) circuit to protect itself against excessively high input voltages. It also has a Negative Voltage Clamp circuit, which protects the device against reverse voltage conditions. Finally, it also has an Over-Temperature Protection circuit that prevents the device from overtemperature conditions.

The LM3404MR/NOPB is a versatile device that can be used in a wide variety of LED lighting applications. It is designed to be easily implemented in any design and can deliver a constant, reliable current to LEDs, making it perfect for automotive, architectural, and message board lighting applications, among others.

In summary, the LM3404MR/NOPB is a member of the PMIC - LED Driver family of integrated circuits, specifically designed for high-power LED lighting applications. It is a versatile device, with an adjustable current regulator, over-voltage and over-temperature protection, and an input voltage range of 4.8V to 55V. The LM3404MR/NOPB is an ideal choice for designers of automotive, architectural, signage, and replacement lamp/downlight LED lighting systems.
