LM2575HVMX-15/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVMX-15/NOPB is a SIMPLE SWITCHER step-down voltage regulator from Texas Instruments. It operates with an input voltage range of 4V to 60V and provides a fixed 15V output at up to 500mA. The device utilizes a buck topology with a typical switching frequency of 52kHz. It is housed in a SOIC-14 package and supports junction temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch for simplified design
• Fixed 15V output option eliminates external feedback components
• Internal frequency compensation reduces external component count

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power systems
• Pre-regulators for switching regulators
• Efficient on-board regulation before linear regulators

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'HVMX' corresponds to the SOIC-14 package variant, distinct from TO-263 or TO-220 packages. Confirm RoHS compliance via the 'NOPB' designation. Ensure the specific distributor listing matches the manufacturer part number exactly to avoid pinout mismatches between different package types within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 15V output is required rather than adjustable regulation. The SOIC-14 package offers surface-mount convenience compared to through-hole options. Verify that the 500mA load current meets application demands, as higher current variants exist in the family. Check thermal requirements for the SOIC-14 package under expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 SIMPLE SWITCHER family, designed for high-efficiency DC-DC conversion. The 'HV' indicates high-voltage input capability up to 60V. The 'MX' suffix specifies the SOIC-14 tape-and-reel packaging, distinguishing it from other physical form factors like D2PAK or TO-220 available in the same electrical series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2575HVMX-15/NOPB is the direct lead-free replacement for the non-compliant LM2575HVMX-15. Cross-package replacements such as LM2575S-15/NOPB require PCB layout modifications due to different pinouts.
