LM2674LDX-5.0/NOPB - Texas Instruments

The LM2674LDX-5.0/NOPB is a highly efficient, space-conscious step-down voltage regulator designed by Texas Instruments. This regulator is part of the SIMPLE SWITCHER® family and is known for its ease of use and robust performance. The device is capable of delivering up to 500 mA of continuous output current with an input voltage range from 8 V to 40 V, making it suitable for a wide range of applications, from automotive to industrial systems.

One of the key features of the LM2674LDX-5.0/NOPB is its fixed 5V output voltage, which provides a stable and regulated power supply for circuits that require a consistent 5V source. It employs a PWM (Pulse Width Modulation) switching technique, which ensures high efficiency over a wide load range. This efficiency minimizes the need for heat sinks and reduces the thermal footprint of the device, making it ideal for space-constrained applications.

The regulator comes in a low-profile, surface-mountable TO-252 (known as D-Pak) package, which is highly favored for its small size and ease of integration into various circuit designs. The NOPB designation indicates that the product is lead-free (No Lead (Pb)), aligning with environmental standards and regulations such as RoHS.

Additional features of the LM2674LDX-5.0/NOPB include a low quiescent current, which enhances its efficiency during light load conditions, and a shutdown mode that reduces the quiescent current to a negligible level, further conserving power when the device is not in active use. The regulator also incorporates built-in protection features such as thermal shutdown, current limit, and overvoltage protection, safeguarding the device and the downstream components from potential damage due to abnormal operating conditions.

With its combination of efficiency, compact packaging, and protection features, the LM2674LDX-5.0/NOPB from Texas Instruments stands out as a reliable and convenient solution for designers looking to manage power in their electronic systems efficiently.
