LM2590HVT-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2590HVT-5.0/NOPB is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments, operating at a fixed switching frequency of 150 kHz. It provides a fixed output voltage of 5.0 V with a maximum output current capability of 1 A. The device supports an input voltage range from 4.5 V to 60 V and utilizes a TO-263 (D²PAK) surface-mount package. It functions as a buck converter topology suitable for high-voltage applications.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch rated for 1 A continuous load current
• Fixed internal switching frequency of 150 kHz for simplified external component selection

• Built-in thermal shutdown protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial systems
• Battery-powered equipment requiring high input voltage steps
• General-purpose DC/DC conversion modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus 'S' for tube, as this affects handling and reflow profiles. Confirm RoHS compliance status via the manufacturer's official datasheet or ordering information page 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. Ensure the application demands a maximum load current of 1 A. Consider the TO-263 package for its thermal dissipation capabilities in space-constrained designs compared to smaller packages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2590HV series of SIMPLE SWITCHER regulators. It shares functional similarities with the LM2596 series but offers higher input voltage support. The device integrates the control circuitry and power switch into a single monolithic IC to reduce external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2590HV variants with different output voltages or adjustable versions like LM2590HVSX-ADJ/NOPB. Cross-reference pinouts and thermal characteristics when replacing with non-TI equivalents.
