LM2596SX-ADJ Description

Short technical summary and product information.

The Texas Instruments LM2596SX-ADJ is a robust DC/DC switching regulator designed for step-down voltage conversion. This voltage-mode regulator operates at a fixed frequency of 150kHz and can deliver up to 3A of output current.

 

With an input voltage range from 4.5V to 40V, the LM2596SX-ADJ offers flexibility for various power supply designs. The output voltage is adjustable, allowing for precise voltage regulation tailored to specific application needs. Key electrical features include over-current protection and a typical quiescent current of 0.005A.

 

This component is available in a surface mount package, specifically the DDPAK/TO-263-5 (TO-263-6, D²Pak (5 Leads + Tab), TO-263BA). The operating temperature range is -40°C to 125°C (TJ), making it suitable for a wide array of environmental conditions. Its design emphasizes low component count and high efficiency, simplifying power supply implementation.
