LM2676SX-ADJ/NOPB Description

Short technical summary and product information.

The LM2676SX-ADJ/NOPB from Texas Instruments is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It is capable of driving loads up to 3A and operates within a wide input voltage range of 8V to 40V.

This regulator features a fixed internal oscillator operating at 260kHz, simplifying design with off-the-shelf external components. The output is adjustable, providing flexibility for various power supply designs. It is housed in a TO-263-7 surface-mount package.

Key electrical specifications include a 3A output current and an 8V to 40V input voltage range. The operating temperature range is -40°C to 125°C (TJ). The device utilizes a buck topology and does not have a synchronous rectifier.
