LM2592HVSX-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2592HVSX-5.0/NOPB is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a step-down voltage regulator with buck topology. It delivers a fixed 5 V output at up to 2 A current capability. The device operates within an input voltage range of 4.5 V to 60 V and features a switching frequency of 150 kHz. It supports shutdown functionality and includes internal compensation for minimal external component requirements. The unit is housed in a TO-263-6 (D2PAK) surface-mount package and operates across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic switching regulator designed for high-efficiency step-down conversion
• Fixed 5 V output option eliminates external resistor divider requirements
• Internal frequency compensation reduces the need for additional external components
• Thermal shutdown protection safeguards against overheating during operation

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power systems requiring efficient voltage regulation
• Direct conversion from 12 V bus voltages
• Pre-regulators for switching post-regulator modules
• Efficient on-card regulation for board-level distribution

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the specific suffix X indicates tape-and-reel packaging rather than tube configuration when reviewing ordering information. Confirm the NOPB designation ensures compliance with RoHS standards and absence of specified hazardous substances. Cross-reference the manufacturer part number against official Texas Instruments documentation to ensure authenticity and correct revision level before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5 V output is required with up to 2 A load capacity. The 150 kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Ensure the input voltage does not exceed 60 V. Consider thermal management requirements due to the TO-263 package's heat dissipation characteristics under high load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2592HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with other members like the LM2592HVS but differs in packaging format. The 'X' suffix denotes reel-based packaging suitable for automated assembly processes, distinguishing it from the 'S' variant which typically uses tube packaging.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2592HVS-5.0/NOPB offers identical electrical performance but utilizes tube packaging instead of tape-and-reel.
