LM2591HVT-ADJ/LF16

Voltage Regulators - DC DC Switching Regulators Overview

The LM2591HVT-ADJ/LF16 is a monolithic integrated circuit from the Texas Instruments LM2591HV series, functioning as a step-down (buck) switching voltage regulator. It operates at a fixed switching frequency of 150 kHz and delivers an output current capability of 1 A. The device accepts an input voltage range of 4.5 V to 60 V and provides a positive adjustable output voltage ranging from 1.2 V to 57 V. Designed for high-voltage applications, it utilizes TO-220-5L formed leads packaging and supports operation across a junction temperature range of -40°C to +125°C.
