LM2574HVMX-15

Voltage Regulators - DC DC Switching Regulators Overview

The LM2574HVMX-15/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments, designed for high-voltage input applications up to 60V. It provides a fixed 15V output with a maximum current of 500mA. The device operates within an input voltage range of 4V to 60V and features a switching frequency of approximately 52kHz to 58kHz. It supports both Buck and Inverting topologies. The component is housed in a SOIC-Wide-14 package and functions reliably across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated monolithic power switch capable of handling high input voltages up to 60V
• Fixed 15V output configuration ensuring stable regulation without external feedback adjustments
• Supports buck (step-down) and inverting circuit topologies for versatile power conversion needs

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial control systems requiring isolated or inverted voltage rails
• High-voltage DC-to-DC conversion modules
• Power supplies for equipment operating with wide input voltage ranges

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix /NOPB indicates lead-free compliance and RoHS adherence. Confirm the specific output voltage version matches the design requirement, as the LM2574HV series includes multiple fixed voltage options. Ensure the SOIC-Wide-14 package footprint aligns with the PCB layout specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15V output is required from inputs up to 60V. It is suitable for designs needing moderate current capability around 500mA. Consider the thermal performance in the SOIC-14 package if operating near maximum load conditions. Verify that the switching frequency compatibility does not interfere with sensitive analog sections in the system.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574HV family of SIMPLE SWITCHER regulators, which are optimized for high-input voltage applications compared to standard LM2574 variants limited to 40V. The 'HVMX' designation identifies the high-voltage variant in the SOIC-14 surface-mount package. The '/NOPB' suffix confirms the absence of halogenated flame retardants and lead-free construction.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2574HVMX-15/NOPB is the direct equivalent. LM2574HVMX-15 may be available but requires verification of environmental compliance status.
