LM2595SX-5.0/NOPB Description

Short technical summary and product information.

LM2595SX-5.0/NOPB is a step-down (buck) switching voltage regulator from Texas Instruments. This fixed-output version delivers a regulated 5V output and is rated for continuous load currents up to 1A.

 

The regulator accepts a wide input voltage range of 4.5V to 40V and operates at a fixed 150kHz switching frequency. It uses voltage-mode control and a non-synchronous rectifier topology. An enable pin, overcurrent protection, and a maximum duty cycle of 100% are included. The junction operating temperature range is -40°C to 125°C.

 

This 5V fixed-output regulator is suited for point-of-load regulation, general-purpose power conversion, and battery-powered systems where a stable 5V rail is needed from a higher supply. The internal fixed feedback network removes the need for external divider resistors, simplifying the BOM.

 

The device is packaged in a TO-263-6 (D²Pak) surface-mount package with 5 leads and a tab, suitable for power dissipation at 1A output levels.
