Product Overview: LM2676SD-5.0/NOPB

The LM2676SD-5.0/NOPB is a highly efficient, step-down voltage regulator designed and manufactured by Texas Instruments. This component 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 3A of continuous output current with an input voltage range from 8V to 40V, making it suitable for a wide range of applications.

The LM2676SD-5.0/NOPB operates at a fixed frequency of 260kHz, which allows for a smaller-sized inductor and capacitors, resulting in a compact power supply design. This regulator features an internal switch with a low on-resistance, ensuring high efficiency across the full load range. The fixed 5.0V output voltage version simplifies the design process, as no external feedback resistors are needed.

The device comes in a thermally enhanced, surface-mount TO-263 package, which is designated by the 'SD' in its part number. The NOPB suffix indicates that this product is lead-free and RoHS compliant, aligning with environmental standards and regulations. With its built-in protection features such as thermal shutdown, current limit, and output over-voltage protection, the LM2676SD-5.0/NOPB ensures safe operation under various conditions.
