LM2575HVM-12/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVM-12/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 12V output at up to 1A load current. The device integrates a 1A power switch and operates at a typical switching frequency of 52kHz. It utilizes the TO-263 (D²PAK) package for surface-mount applications, supporting operation temperatures from -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated high-voltage 1A power switch eliminates external component requirements
• Fixed 12V output option simplifies design without external feedback resistors
• Internal frequency compensation reduces external component count
• Built-in thermal shutdown protects against overheating

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for industrial equipment
• Pre-regulator stages for switching regulators
• Battery-powered systems requiring high input voltage tolerance

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free status and RoHS compliance as per Texas Instruments documentation. Ensure the ordering part number matches the exact package type required for your PCB footprint. Cross-reference the manufacturer datasheet revision to confirm pinout compatibility before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from a wide input voltage range up to 60V. The TO-263 package offers better thermal performance than smaller SOT packages for continuous 1A loads. Consider the internal 52kHz switching frequency for standard inductor selection guidelines provided in the official datasheet.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of SIMPLE SWITCHER regulators. The 'HV' designation indicates high-voltage input capability up to 60V. The 'M' suffix typically denotes the TO-263 surface-mount package variant within the product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2575HVM-12 and LM2575HVMX-12. Verify pinout and thermal pad configurations match the existing board layout. Alternative fixed-output voltages require changing the suffix number while maintaining the HV and M package codes.
