LM2592HVT-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2592HVT-5.0 is a SIMPLE SWITCHER power converter functioning as a buck switching regulator IC with a positive fixed 5V output. It supports up to 2A output current and operates at a switching frequency of 150 kHz. The device accepts an input voltage range from 4.5 V to 60 V, with a nominal input of 12 V. It is housed in a TO-220-5 package with formed leads and functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic switching regulator designed for step-down voltage conversion
• Fixed internal feedback network ensures stable 5V output without external adjustment components
• Operates at a standard 150 kHz switching frequency to optimize passive component size

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring high efficiency step-down conversion
• On-card regulation for bus voltages in industrial or commercial equipment
• Pre-regulator stages for switching regulators operating downstream

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets are managed by Texas Instruments. Confirm the specific suffix (e.g., NOPB) indicates lead-free compliance if required. Ensure the TO-220-5 package type matches the thermal and mechanical constraints of the target PCB design. Cross-reference datasheet revisions to confirm pinout consistency across production batches.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from an input voltage up to 60V. The 2A current rating suits moderate load applications where thermal dissipation in a TO-220 package is manageable. Consider the 150 kHz frequency for balancing component size against electromagnetic interference requirements compared to lower frequency alternatives.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2592HV series of SIMPLE SWITCHER converters. It is a higher voltage variant capable of handling inputs up to 60V, distinguishing it from standard LM2592 models. The 'HVT' designation typically refers to the through-hole TO-220 package version, while other suffixes may indicate surface-mount options like TO-263.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2592HVT-5.0/NOPB is the direct lead-free compliant equivalent. LM2592HVT-ADJ serves as a functional replacement if adjustable output voltage is needed instead of fixed 5V.
