LM2594HVMX-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVMX-5.0/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, housed in an SOIC-8 surface-mount package. It operates with a fixed 5 V output and supports up to 500 mA load current. The device accepts input voltages ranging from 4.5 V to 60 V and switches at a nominal frequency of 150 kHz. Quiescent current is typically 5 mA. It functions within a temperature range of -40°C to +125°C and includes integrated shutdown control.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch enables direct connection to standard 48 V bus supplies.
• Fixed internal switching frequency eliminates the need for external timing components.
• Built-in thermal shutdown protects against overheating during fault conditions.

Voltage Regulators - DC DC Switching Regulators Applications
