LM2594HVM-5.0/NOPB

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 150 kHz switching frequency. It accepts an input voltage range of 4.5 V to 60 V and provides a fixed 5 V output with a maximum current capability of 500 mA. The device utilizes a buck topology and features a shutdown pin for power management. It is housed in an 8-pin SOIC surface-mount package and supports operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage switch enables direct connection to high-voltage bus systems 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 high-voltage input conversion
• Battery-powered systems utilizing lead-acid or nickel-cadmium sources
• Industrial control circuits needing isolated or non-isolated DC-DC conversion

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free compliance and RoHS status. Ensure the ordering code matches the specific package variant (SOIC) and output configuration (Fixed 5V). Cross-reference the manufacturer's latest datasheet for any updates regarding recommended operating conditions or application circuit requirements before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from a high-voltage source up to 60 V. It is suitable for applications where moderate output current around 500 mA is sufficient. Consider the SOIC package constraints for thermal dissipation and PCB layout space. Compare against adjustable variants if flexible output voltage is needed, or higher current devices if load demands exceed 500 mA.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2594HV series of SIMPLE SWITCHER regulators, designed for high-input voltage applications. It shares architectural similarities with other members like the LM2594HVM-ADJ but differs in its fixed output configuration. The series is characterized by its simplicity, requiring minimal external components for basic operation, making it a standard choice for efficient step-down conversion in industrial and commercial electronics.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2594HVMX-5.0/NOPB serves as a reel-based alternative to the tube-packaged LM2594HVM-5.0/NOPB. Both share identical electrical characteristics and functionality. Verify packaging preferences during substitution. Other family members like LM2594MX-5.0/NOPB offer different package options but maintain similar performance profiles.
