Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2574HVMX-ADJ/NOPB

LM2574HVMX-ADJ/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2574HVMX-ADJ/NOPB is a SIMPLE SWITCHER® 0.5A step-down voltage regulator from Texas Instruments, housed in a 14-pin SOIC-Wide package. It supports an input voltage range of 4V to 60V and delivers up to 500mA output current. The device features a fixed switching frequency of 58kHz and adjustable output voltage via external resistors. Operating temperature ranges from -40°C to +125°C with a typical quiescent current of 5mA.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated power switch eliminates the need for external components
Adjustable output voltage controlled by two external resistors
Internal frequency compensation simplifies design requirements
Thermal shutdown protects against overheating conditions

Voltage Regulators - DC DC Switching Regulators Applications

Distributed power supply systems
Direct conversion from bus voltages
Simple step-down DC/DC converters

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'NOPB' confirms lead-free and RoHS compliance status. Ensure the 'HV' designation matches the required 60V input capability rather than standard 40V variants. Confirm the 'MX' suffix indicates tape-and-reel packaging suitable for automated assembly processes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed 40V but remain below 60V. Choose the adjustable version for flexible output requirements. Consider thermal performance at high loads due to the SOIC-14 package limitations compared to larger packages.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574HV series, designed for high-voltage applications. It complements the standard LM2574 which supports only up to 40V input. The family offers both fixed and adjustable output options for various industrial needs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2574HVMX-ADJ/NOPB serves as the direct equivalent without the NOPB suffix. LM5574 provides similar functionality with different pinout or specifications.
