LM2575HVN-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575HVN-5.0 is a monolithic integrated circuit from the SIMPLE SWITCHER family, functioning as a step-down (buck) switching voltage regulator. It provides a fixed 5V output with a maximum load current of 1A. The device supports an input voltage range from 4V to 60V, enabling operation in high-voltage applications. It utilizes a fixed 52kHz internal oscillator and requires minimal external components for implementation. The unit is housed in a TO-220-5 through-hole package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrated fixed-frequency oscillator simplifies design by reducing external component count
• Built-in frequency compensation eliminates the need for external loop compensation networks
• Includes thermal shutdown and cycle-by-cycle current limiting for fault protection
• Supports external shutdown control to minimize standby power consumption

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring buck conversion
• Pre-regulator stages for linear post-regulators
• Efficient battery-powered systems operating from higher voltage sources

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'N' indicates the non-rohs or legacy variant if required, though 'NOPB' denotes lead-free compliance. Confirm the manufacturer source is Texas Instruments or authorized distributor. Check datasheet revision history for any pinout or electrical parameter updates before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output is required from an input voltage up to 60V. The TO-220 package suits applications needing through-hole mounting and moderate heat dissipation without active cooling. Ensure the application current does not exceed 1A continuous load limits under specified ambient temperature conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 series of SIMPLE SWITCHER regulators, designed to replace traditional three-terminal linear regulators. The HV variant specifically extends the maximum input voltage capability compared to standard versions, allowing direct connection to higher voltage buses such as 48V industrial systems.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2575T-5.0/NOPB: Standard voltage version limited to 40V input; verify input requirements. LM2596T-ADJ/NOPB: Higher current capacity but adjustable output configuration.
