LM2590HVS-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2590HVS-5.0/NOPB is a fixed-output step-down switching regulator from the Texas Instruments SIMPLE SWITCHER family, designed for high-voltage applications. It operates with an input voltage range of 4.5 V to 60 V and provides a stable 5 V output at up to 1 A load current. The device integrates a 150 kHz fixed-frequency oscillator and utilizes a TO-263-7 surface-mount package. It supports operation across an extended temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a monolithic buck converter topology for efficient step-down voltage conversion
• Features a fixed 150 kHz internal oscillator to minimize external component count
• Includes thermal shutdown and current limiting protection mechanisms

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation in industrial control systems
• High-voltage battery-powered equipment power stages
• Distributed power supply architectures requiring 5 V rails

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' indicates lead-free/RoHS compliance and 'Pb-Free' status as per manufacturer documentation. Confirm the 'S' variant designation corresponds to the TO-263-7 package outline. Ensure ordering specifications match the required fixed 5.0 V output tolerance and operating temperature range limits defined in the official datasheet.

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. The 1 A current capability suits moderate load applications. Consider the TO-263-7 package for thermal management needs. Verify that the 150 kHz switching frequency aligns with electromagnetic interference constraints and inductor selection requirements for the target design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2590HV series, which extends the standard LM2590 functionality to higher input voltages. It serves as a direct replacement for lower-voltage regulators in high-input scenarios. The SIMPLE SWITCHER branding denotes integrated controller and power switch technology within a single IC package.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2590HVSX-5.0/NOPB offers identical electrical performance in a tape-and-reel packaging format instead of tube.
