The LM2758TL/NOPB is a highly versatile and efficient PMIC – LED Driver for power management. The device utilizes a low power low voltage operating scheme that enables high efficiency, low noise and thermo-protection. The LM2758TL/NOPB includes features such as dimmable LED operation, LED thermal protection and LED over voltage protection. It consists of an LED driver and a highly efficient current-mode power converter.

The LM2758TL/NOPB is an integrated LED driver solution for driving several LEDs in series. Its features include maximum current protection, undervoltage lockout and soft-start to reduce inrush current on power up. The device also includes a Constant Current dimmer with adjustable voltage and current setting. The LED driver also has a zero mode in which it will operate without any output current. This mode is used for low power standby.

The device uses a constant current control scheme for more accurate LED current control. The LED current is set via an external resistor. This results in better power efficiency, which in turn reduces overall system costs. The LM2758TL/NOPB has an internal logic control that enables it to automatically switch between various operating modes.

Another important feature of the LM2758TL/NOPB is its thermal protection. This feature helps prevent overheating of the device due to excessive current or voltage. The device will automatically reduce the current drawn to avoid any damage caused by thermal runaway.

This device is a perfect solution for systems where low ripple, low noise and high efficiency are important. It is used in applications such as dimmable LED lighting, automotive lighting, and household lighting. It is also used in applications such as cell-phone lighting, TV backlighting, and other mobile device backlighting.

Overall, the LM2758TL/NOPB is an excellent PMIC – LED driver that can be used in a wide range of applications. It offers several features such as dimming, thermal protection and current-mode power conversion. Its precise current control, low power operation and zero mode make it an ideal solution for energy-efficient systems.
