LM2593HVSX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2593HVSX-ADJ/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-down voltage regulator. It operates with a fixed switching frequency of 150 kHz and supports an input voltage range from 4.5 V to 60 V. The device delivers a maximum output current of 2 A with an adjustable output voltage ranging from 1.2 V to 57 V. Housed in a TO-263 (D2PAK) surface-mount package, it is designed for efficient DC-DC conversion within a junction temperature range of -40°C to +125°C.
