LM2596SX-ADJ/ELLI955

Voltage Regulators - DC DC Switching Regulators Overview

The LM2596SX-ADJ/ELLI955 is a SIMPLE SWITCHER® step-down voltage regulator manufactured by Texas Instruments. It operates with an input voltage range of 4.5 V to 40 V and provides a maximum output current of 3 A. The device features a fixed switching frequency of 150 kHz, allowing for the use of compact external components. It supports adjustable output voltages from 1.2 V to 37 V. The component is housed in a TO-263 (D²PAK) surface-mount package with five pins and a thermal tab. It is designed for operation across a junction temperature range of -40°C to +125°C.
