LM2590HVS-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2590HVS-5.0/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, operating at a fixed 150 kHz switching frequency. It provides a fixed 5 V output with a maximum output current of 1 A. The device utilizes a buck topology and accepts an input voltage range from 4.5 V to 60 V. It is housed in a TO-263-7 surface-mount package and supports an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch rated for up to 60 V input
• Fixed 150 kHz internal oscillator eliminates external timing components
• Built-in thermal shutdown and current limit protection

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial systems
• Pre-regulation for DC/DC modules
• Efficient step-down conversion from higher voltage buses

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance. Confirm the '-5.0' designation matches the required 5 V fixed output. Ensure the package type corresponds to TO-263-7 (DDPAK) for proper footprint compatibility during procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required from inputs up to 60 V. It is suitable for applications needing 1 A continuous current without adjustable feedback networks. Consider the TO-263-7 package for thermal management needs in space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2590HV series of SIMPLE SWITCHER converters. It shares the core architecture with other variants in the family but is distinguished by its fixed 5 V output setting and specific pinout configuration within the TO-263-7 package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2590HVS-5.0/NOPB serves as a direct replacement for older National Semiconductor versions. Verify pin compatibility with legacy designs using the LM2590HV series.
