LM2591HVS-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2591HVS-ADJ/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, operating as a step-down voltage regulator with a fixed switching frequency of 150 kHz. It accepts an input voltage range of 4.5 V to 60 V and provides an adjustable output voltage spanning from 1.2 V to 57 V. The device delivers a maximum output current of 1 A through a single output channel. Designed for surface-mount installation in a TO-263-5 package, it functions reliably within an operating temperature range of -40°C to +125°C.
