The LM2674LD-ADJ/NOPB is a versatile, easy-to-use, high efficiency, step-up DC-to-DC switching regulator. This device provides a high current output at a wide input voltage range and is capable of controlling the output current and load to prevent overloads or short-circuits. The LM2674LD-ADJ/NOPB allows users to adjust voltage levels and modify the frequency of the output signal, making it suitable for various applications. The device features an internal oscillator, an adjustable feed-back control, an adjustable current limit, an over-voltage protection, a shutdown/enable input, and an over-temperature protection.

To meet the application requirements, the LM2674LD-ADJ/NOPB provides two types of power supply: an adjustable version (LM2674LD-ADJ) and a fixed 3.3V version (LM2674LD-NOPB). This makes it suitable for a variety of situations, from a high-efficiency DC-DC regulator to a low-cost, low-power voltage regulator.

The high efficiency of the device is achieved by the use of its switching frequency which is usually adjustable to accommodate different system performance objectives. The output can be steplessly adjusted between 1.212V and 5.50V and the output voltage is accurately regulated even if the input voltage varies. It can also be used for non-standard applications such as automotive, industrial, and consumer electronics.

The current limit of the device can be adjusted according to the application requirements. The device can also control the over current protection by setting the Triac latch parameters. When the current limit is exceeded, the Triac limit responds and limits the output current. Besides that, the over voltage protection is provided to prevent the output from exceeding the specified voltage.

In addition, the shutdown/enable input pin of the device can be used to shut down the device, thus reducing power when the DC-DC regulator is not in use. The device also has an over-temperature protection to prevent it from overheating and damaging. The LM2674LD-ADJ/NOPB also supports PWM control, allowing users to control its output voltage with a low-frequency pulse.

The LM2674LD-ADJ/NOPB is designed specifically for portable and battery-powered applications, such as laptop computers, mobile phones, digital cameras, and other consumer electronic devices. Moreover, its high efficiency, low noise, and high reliability makes it suitable for a wide range of industrial, power, and consumer electronics applications.
