Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575-5.0BU TR

LM2575-5.0BU TR

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575-5.0BU TR is a monolithic integrated circuit step-down switching regulator manufactured by Microchip Technology, designed for high-efficiency DC-DC conversion. It provides a fixed 5V output with a maximum load current of 1A, operating within an input voltage range of 4V to 40V. The device utilizes a buck topology with a typical switching frequency of 52kHz and supports both surface-mount (TO-263-5) and through-hole (TO-220-5) installations. It features built-in frequency compensation, thermal shutdown, and current limit protection, requiring minimal external components for operation.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a fixed-frequency oscillator and internal frequency compensation to simplify design requirements.
Includes comprehensive protection mechanisms such as thermal shutdown and cycle-by-cycle current limiting.
Offers high efficiency compared to linear regulators, reducing heat dissipation needs.

Voltage Regulators - DC DC Switching Regulators Applications

High-efficiency step-down switching regulators
Linear regulator pre-regulators for improved performance
Positive-to-negative voltage inversion circuits

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'BU' against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS standards and moisture sensitivity levels required for your assembly process. Cross-reference ordering information directly with the manufacturer's datasheet to avoid discrepancies in pinout or electrical characteristics.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output at up to 1A is required from an input voltage between 4V and 40V. Consider its 52kHz switching frequency for balancing component size and efficiency. Evaluate the TO-263-5 package for surface-mount applications requiring robust thermal performance without additional heatsinks under moderate loads.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 series of switching regulators, originally developed by National Semiconductor and now produced by Microchip Technology. The series is widely recognized for replacing traditional three-terminal linear regulators in various power supply designs, offering significant improvements in efficiency and thermal management for industrial and commercial applications.
