The LM27961TLX/NOPB is a PMIC -LED driver. It is an efficient and reliable solution in the market today for driving one or more LEDs with high power. The LM27961TLX/NOPB has many advantages, such as low noise, high accuracy, low power consumption and robust insulation, which makes it suitable for a wide range of applications.

The LM27961TLX/NOPB is designed to drive high power LEDs, such as those commonly found in automotive lighting, television backlights, signs, general illumination, and other applications. It can be used as an LED driver for any one- or two-channel LED lighting design, or as an isolated or integrated LED lighting system for a variety of lighting applications.

The LM27961TLX/NOPB features a switching buck regulator that operates in continuous current mode. A steady output current is maintained using a control loop circuit based on a sense resistor. The current sense resistor is connected externally and is used to sense the current flowing through the LEDs. The current through the LEDs is then limited to the desired level by controlling the output voltage of the regulator.

The LM27961TLX/NOPB provides an adjustable current limit, allowing users to set the output current according to their application needs. In addition, the device also features high reliability, with a maximum output voltage rating up to 250V and an operating temperature range of -55°C to 125°C.

The LM27961TLX/NOPB also features many other protection functions, such as over-voltage protection, under-voltage protection, thermal shutdown, and two-level over-current protection. These protection functions ensure that the device is used safely and reliably in various applications. Additionally, the device includes an enable/disable pin to shut off the regulator in the event of a fault.

The LM27961TLX/NOPB is widely used for automotive lighting, backlighting for LCD displays, signage, and general lighting applications. It offers a reliable, efficient solution for powering one or more high-power LEDs, with its long working life, high accuracy, and low power consumption making it ideal for these types of applications.
