LM2596SX-ADJ/NOPB Description

Short technical summary and product information.

The LM2596SX-ADJ/NOPB from Texas Instruments is a 3A step-down (buck) switching regulator designed for low component count and high efficiency. It features an adjustable output voltage, allowing for flexible power supply designs.

 

This regulator operates with an input voltage range from 4.5V to 40V and can deliver up to 3A of output current. The fixed internal oscillator operates at 150kHz, simplifying design and utilizing readily available standard inductors. Key electrical features include over-current protection and a TTL shutdown capability for power management.

 

The LM2596SX-ADJ/NOPB is available in a TO-263-6, D²Pak (5 Leads + Tab), TO-263BA package, suitable for surface mount applications. Its operating temperature range is -40°C to 125°C (TJ), making it suitable for various environmental conditions. The device also includes thermal shutdown and current-limit protection for enhanced reliability.
