LM2575HVS-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVS-5.0 is a SIMPLE SWITCHER® 1A step-down voltage regulator from Texas Instruments, designed for high-voltage input applications up to 60V. It operates in a buck topology with a fixed 5.0V output and supports an output current of 1A. The device features a switching frequency of 52kHz and functions within a temperature range of -40°C to +125°C. It is housed in a TO-263-5 (D²PAK) surface-mount package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated power switch enables efficient step-down conversion without external driver requirements.
• Fixed 5.0V output eliminates the need for external feedback resistors for standard regulation.
• Internal frequency compensation simplifies design by reducing required external component count.

Voltage Regulators - DC DC Switching Regulators Applications

• High-voltage to low-voltage DC-DC conversion systems
• Pre-regulation stages for downstream linear regulators
• Point-of-load power supplies in industrial equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm pinout compatibility and thermal performance specifications. Ensure the procurement channel provides genuine components with traceable manufacturing dates to avoid counterfeit risks associated with legacy power management ICs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this model when a fixed 5V output is required from inputs exceeding 4V. The TO-263-5 package offers superior thermal dissipation compared to smaller footprints. Confirm that the 1A continuous current rating meets the load requirements, as higher currents may necessitate alternative packages or derating strategies.
