LM2574HVMX-15/NOPB

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 60 V. It provides a fixed 15 V output with a maximum load current of 500 mA. The device operates at a switching frequency of 58 kHz and features an internal power switch rated for 1.8 A. It supports Buck and Inverting topologies within an operating temperature range of -40 °C to +125 °C. The component is housed in a SOIC-Wide-14 package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage power switch capable of handling up to 1.8 A
• Fixed 15 V output configuration for simplified design
• Supports both Buck and Inverting circuit topologies

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial control systems requiring isolated or inverted supply rails
• High-voltage battery-powered equipment
• Distributed power conversion architectures

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'HVMX' indicates the tape-and-reel packaging variant rather than tube packaging. Confirm the 'NOPB' designation ensures compliance with lead-free manufacturing standards. Cross-reference the manufacturer part number against official datasheets to ensure compatibility with required thermal and electrical specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15 V output is required from inputs up to 60 V. The high-voltage capability distinguishes it from standard LM2574 variants limited to 40 V. Ensure the PCB layout accommodates the SOIC-Wide-14 package dimensions and thermal requirements for continuous 500 mA operation at elevated ambient temperatures.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574HV series, which extends the standard SIMPLE SWITCHER family to handle higher input voltages. Unlike the standard LM2574M or LM2574N versions limited to 40 V inputs, the HV variant supports up to 60 V. The MX suffix specifically denotes surface-mount reel packaging, differentiating it from through-hole or tube-packaged equivalents.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2574HVMX-15/NOPB is functionally identical to LM2574HVMX-15 but includes the NOPB suffix indicating lead-free construction. Direct substitutes include other LM2574HV-15 variants with compatible packaging.
