LM2796TLX/NOPB: PMIC - LED Drivers

The LM2796TLX/NOPB is an integrated LED driver module, also known as a power management integrated circuit (PMIC) LED driver. It is designed to drive multiple LED strings and is capable of handling high power and voltage levels with very low EMI. This makes it perfect for industrial and medical applications.

The LM2796TLX/NOPB application field and working principle is based on the theory of light emitting diodes (LEDs). LEDs are semiconductor light sources that are extremely efficient, resulting in reduced energy consumption and longer LED life. The LED driver module uses this efficiency to regulate the power input for driving LED strings with high power and high voltage levels.

To capture the efficiency of LEDs, the LM2796TLX/NOPB LED driver module employs a switching regulator topology, similar to a buck-boost converter. The LM2796TLX/NOPB contains a high-side MOSFET and a low-side MOSFET control IC. Power is supplied to the MOSFET control IC through the active power input port. When the input voltage is higher than the programmed voltage limit, the high-side MOSFET is switched on and the current is transferred to the output of the LM2796TLX/NOPB.

The LM2796TLX/NOPB is configured through the inherent protection features, including an enable pin that is used to enable or disable the regulator. A back-bias pin is used to regulate the power transfer from the input supply to the regulated output. The regulated output can also be configured using the DAC channel and an internal temperature-compensation circuit. Additionally, the module can be configured with an over-voltage lockout and an inverse-current watchdog.

The LM2796TLX/NOPB is ideal for applications such as medical imaging, LCD panel backlighting, strobe lights, automotive lighting and lighting for general purpose. It is suitable for use in temperature ranges up to 140°C and operating voltage range up to 40V. Its programmable power capabilities, protection features and overall integration make it the ideal choice for various lighting applications.

To sum up, the LM2796TLX/NOPB is an integrated LED driver module that is used to drive multiple LED strings with high power and voltage levels, while maintaining low EMI. With its integrated protection features and programmable power capabilities, the LM2796TLX/NOPB is an ideal solution for a wide range of LED based applications.
