DC Switching Voltage Regulators

LM2675N-5.0/NOPB Description

The LM2675N-5.0/NOPB from Texas Instruments is a fixed 5V, 1A output buck (step-down) switching voltage regulator, part of the SIMPLE SWITCHER® series. Designed for efficiency and simplicity, it operates over a wide input voltage range of 6.5V to 40V, making it suitable for industrial, automotive, and consumer applications. With a switching frequency of 260kHz, it balances performance and component size, reducing the need for large external inductors. The device is housed in an 8-pin DIP (Through Hole) package, ensuring robust mechanical stability. It features non-synchronous rectification and complies with ROHS3 and REACH environmental standards.
