LM2590HVT-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2590HVT-5.0/NOPB is a step-down switching voltage regulator from the Texas Instruments LM2590HV series, designed for high-voltage input applications. It operates with a fixed 5.0 V output and supports up to 1 A of continuous load current. The device utilizes a buck topology and functions at a standard switching frequency of 150 kHz. It is housed in a seven-pin TO-220 through-hole package, suitable for robust thermal management. The component is rated for an operating temperature range from -40 °C to +125 °C and includes internal protection features such as thermal shutdown and current limiting.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch capable of handling input voltages up to 60 V
• Fixed 5.0 V output configuration eliminates external resistor requirements
• Built-in thermal shutdown and cycle-by-cycle current limiting for system reliability

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply architectures requiring high input voltage conversion
• Battery-powered systems with wide input voltage ranges
• Post-regulation stages in general-purpose power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free and RoHS compliance when sourcing. Confirm the HVT designation corresponds to the high-voltage variant with the specified 60 V maximum input rating. Ensure the TO-220-7 package matches the required through-hole mounting specifications for the target PCB design.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from inputs exceeding standard logic levels but below 60 V. The 1 A current limit suits moderate load applications where efficiency and thermal performance are prioritized over compact surface-mount footprints. Compare against the LM2596 series if higher current capacity or different packaging is needed.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2590HV family of SIMPLE SWITCHER power converters. It shares architectural similarities with the LM2576 and LM2596 series but is optimized for higher input voltage tolerance. The 'HVT' suffix distinguishes it from lower-voltage variants within the broader LM2590 product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2590HVT-3.3/NOPB provides a 3.3 V output with identical electrical characteristics. LM2596T-5.0 offers similar functionality but typically requires different external component values due to minor parameter variations.
