LM2672M-ADJ/NOPB

LM2672M-ADJ/NOPB Description

The LM2672M-ADJ/NOPB from Texas Instruments is a high-efficiency, adjustable-output buck (step-down) switching voltage regulator capable of delivering up to 1A of continuous output current. Part of the SIMPLE SWITCHER® series, it operates over a wide 6.5V to 40V input range, making it suitable for industrial, automotive, and consumer applications requiring robust power conversion. The output voltage is adjustable from 1.21V to 37V, providing flexibility for diverse load requirements. With a fixed 260kHz switching frequency, it balances efficiency and component size, minimizing external filter requirements. The device is housed in an 8-pin SOIC package, optimized for surface-mount assembly, and complies with ROHS3 and REACH environmental standards.
