LM2576HVT-15/NOPB - Texas Instruments

The LM2576HVT-15/NOPB is a versatile and robust step-down voltage regulator designed and manufactured by Texas Instruments. This integrated circuit is part of the LM2576 series, which is renowned for its high efficiency, ease of use, and reliability. The LM2576HVT-15/NOPB is specifically engineered to deliver a fixed output voltage of 15V with a high output current of up to 3A, making it an ideal choice for a wide range of applications, including consumer electronics, automotive, and industrial systems.

This regulator operates over a wide input voltage range from 4V to 60V, allowing it to accommodate a variety of power sources, from batteries to unregulated DC power supplies. Its high efficiency is achieved through the use of a simple and efficient buck converter topology, which reduces the amount of heat generated and minimizes the need for external heat sinking.

The LM2576HVT-15/NOPB features a fixed 52 kHz switching frequency, which provides an optimal balance between efficiency and the size of external components. It comes in a TO-220 package, which is known for its good thermal performance and ease of mounting on printed circuit boards. The device also includes built-in protection features such as thermal shutdown, current limit, and safe area compensation, which enhance its reliability and longevity by preventing damage due to overloading or overheating.

One of the key advantages of the LM2576HVT-15/NOPB is its simplicity of design. It requires only a few external components to create a complete power supply solution, including an inductor, diode, and a couple of capacitors. This simplicity, combined with its high performance and integrated features, makes it a popular choice for designers looking to reduce development time and improve system robustness.

The NOPB designation in the part number indicates that this product is lead-free and RoHS compliant, reflecting Texas Instruments' commitment to environmental sustainability. The LM2576HVT-15/NOPB is an excellent solution for anyone needing a reliable, high-performance 15V regulator capable of delivering substantial current while maintaining energy efficiency.
