LM3280TLX-290/NOPB is an integrated power management switch device manufactured by Texas Instruments, and is primarily used in power management applications. This device operates as a switching regulator with a high efficiency step-down DC-DC converter, and a low dropout linear regulator, both of which can be enabled and disabled independently.

The LM3280TLX-290/NOPB is designed to switch between different power sources, allowing control of peripheral supplies independently from main rails. It supports operating ranges from 2.5V to 5.5V and allows a wide selection of output voltage up to 3.3V when used in VDD mode. It also features an output capable of up to 0.8A when used in the bypass mode.

The LM3280TLX-290/NOPB integrates two separate regulator devices, one linear and one switching regulator. The linear regulator includes an internal current limit protection, which prevents overloads while maintaining stable voltage regulation. The switching regulator also includes its own current limit setting, and supports a wide operating range of up to 3.3V when used in the bypass mode. The device also includes two control pins, enabling and disabling the regulators independently of each other.

The LM3280TLX-290/NOPB offers several features to reduce noise and improve switching efficiency. It features a fast internal reference voltage to reduce output voltage regulation noise, and a low-impedance internal feedback to reduce oscillations. In addition, a patented technique known as ripple cancellation allows the device to regulate its output voltage without introducing unwanted noise.

The LM3280TLX-290/NOPB is suitable for applications in automotive and industrial applications, such as motor drives, power supplies and motor control systems. Its small QFN package allows easy integration with other components, and its high efficiency makes it suitable for use in power management circuitry with limited power budget. With its wide operating range, fast reference voltage and low-impedance internal feedback, the LM3280TLX-290/NOPB is ideal for applications that require reliable power management.
