The LM2595T-5.0/NOPB is an adjustable step-down switching regulator from Texas Instruments. It contains all of the necessary features to implement a low cost, adjustable frequency, synchronous buck regulator. It has an input voltage range of 4.5V to 40V, a controlled output voltage as low as 1.23V, and a maximum output current of 3A. Its main features include an on-chip driver, high efficiency, fast transient response, and an enable pin for remote on/off control. Additionally, it is made in a thermally enhanced 8-pin PowerPAD™ Power SOIC package.
