LM2594HVM-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2594HVM-5.0/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, operating at a fixed switching frequency of 150 kHz. It accepts an input voltage range of 4.5 V to 60 V and provides a fixed output of 5 V with a maximum load current of 500 mA. The device utilizes a surface-mount SOIC-8 package and supports operation across an extended temperature range from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch enables direct connection to high-voltage bus supplies without external components.
• Fixed internal feedback network ensures stable 5 V output regulation without requiring external resistors.
• Built-in thermal shutdown and current limit protection safeguard the device under fault conditions.

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply architectures requiring buck conversion from high-voltage rails
• Battery-powered systems utilizing high-voltage battery packs
• Industrial control modules needing isolated or non-isolated DC-DC regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB indicates lead-free compliance and RoHS adherence. Confirm the 'HVM' designation specifies the high-voltage variant capable of handling up to 60 V input. Ensure the '-5.0' code matches the required fixed 5 V output level for your circuit design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from inputs exceeding 4.5 V. The 500 mA current rating suits low-to-medium power applications. Consider the SOIC-8 package constraints for thermal management in enclosed environments compared to higher-current TO-263 alternatives.
