LM3402MR/NOPB is a LED driver IC belonging to the category of PMIC - LED Drivers. It is manufactured by Texas Instruments and its main purpose is to drive LEDs in the range of up to 250 mA. This makes it suitable for applications such as white LED backlight in LCD displays and RGB LED lighting solutions.

The LM3402MR/NOPB comes with a wide input voltage range, from 4.5V to 50V, making it suitable for use in a variety of applications. The device has a slew rate of 3V/us, allowing for fast switching and improved performance. In addition, it has a low dropout voltage of 0.4V. This enables the device to maintain a steady output current even when the input voltage drops below the minimum operating voltage.

The LM3402MR/NOPB has two main operating configurations: Constant Current (CC) mode and Constant Voltage (CV) mode. In CC mode, the output current is maintained constant regardless of the input voltage. This makes it suitable for drivinghigh-power LEDs and white LED backlight solutions. In CV mode, the output voltage is maintained constant regardless of the input voltage. This makes it suitable for low-power LED applications.

The LM3402MR/NOPB also has an adjustable current limiter which can be used to adjust the maximum current that can be drawn from the device. This feature helps to protect the device from over-current conditions and further adds to its flexibility in various applications. The device also has an internal thermal shutdown protection that helps to protect against thermal overloads.

The LM3402MR/NOPB also supports an external shutdown control pin that can be used for either manual or automated shutdown. The device has an enable pin which can be used to enable or disable power output from the device. In addition, it has a power good output pin which indicates when the device is properly powered and ready to operate.

The LM3402MR/NOPB is highly efficient and has a wide operating temperature range of -40°C to +125°C. This makes it suitable for use in both commercial and automotive applications. The device also has a number of safety features including over voltage protection, over current protection and thermal shutdown.

In conclusion, the LM3402MR/NOPB is an ideal solution for driving LEDs in the range of up to 250 mA. It has a wide input voltage range and adjustable current limiter, making it suitable for a variety of applications. The device also has a number of safety features including over voltage protection, over current protection and thermal shutdown. Because of its high efficiency and wide operating temperature range, it can be easily used in both commercial and automotive applications.
