LM27966SQ/NOPB is a LED driver PMIC device, which helps in giving the added power to the LEDs to perform efficiently. It is a dedicated PROFET device from Texas Instruments. The device is built by combining a current−regulating buck-boost DC/DC converter and an On−Time PROFET in the same package. It is made particularly for the applications where no additional driver circuit is wanted for a steady output current for both high and low step voltages.

The LM27966SQ/NOPB application field can be seen in the systems that require power to drive one up to two LEDs with an input voltage range from 6V to 15V. It is used to drive the LEDs in both parallel and series connections. With this, power can be supplied from multiple sources such as lead acid, lithium-ion, and alkaline batteries. It is often used in many automotive and industrial settings, like in the field of kiosk OLED (organic light-emitting diode) lighting, modern dashboards, outdoor lighting, etc. It can also be used in applications that require step-up and step-down of voltages to a precise voltage with high efficiency.

The operating principle of the LM27966SQ/NOPB is quite simple. The device comprises of an adjustable buck-boost DC/DC regulator along with an embedded On-Time PROFET. This combination helps it to regulate a steady current with a precise voltage to the LEDs. The PROFET acts as a switch which controls the voltage across the LEDs together with the output current regulation. The On-Time PROFET works with the help of an on-time circuit that holds the voltage regulation to a maximum. In addition, the device also includes an internal 2.5V precision reference, low feedback voltage passives, enabling soft start and watchdog timer. All these features make the LM27966SQ/NOPB a strongly integrated, high efficiency, and cost-effective driver solution for one or two LEDs.

The LM27966SQ/NOPB is a significant step ahead in terms of performance, flexibility, and cost-effectiveness in the LED driver PMIC devices. The device helps to significantly reduce the circuitry needed for driving the LEDs, making it a viable option when compared to traditional solutions. Its ability to provide precise output currents as well as step-up/step-down of voltages to the LEDs makes it suitable for a variety of applications. In addition, the device also has a wide operating temperature range, making it reliable in extreme temperatures. All these features make the LM27966SQ/NOPB an ideal choice for driving LEDs in industrial and automotive settings.
