Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575WU

LM2575WU

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575WU is a monolithic integrated circuit step-down (buck) switching regulator manufactured by Microchip Technology. It operates with an input voltage range of 4V to 40V and provides a fixed 5V output capable of driving a 1A load. The device utilizes a 52kHz internal oscillator frequency and features a TO-263-5 surface-mount package. It includes internal frequency compensation and protection circuits, supporting operation within a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a fixed 52kHz oscillator for simplified external component requirements
Includes internal current limiting and thermal shutdown protection mechanisms
Provides high efficiency performance reducing the need for extensive heat sinking

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in distributed power supply systems
Pre-regulator stages for linear post-regulators
Efficient buck converters for battery-powered equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'WU' corresponds to the TO-263-5 surface mount package configuration. Confirm RoHS compliance status as regulatory requirements vary by region and manufacturing date code. Ensure the ordering part number matches the required 5V fixed output variant rather than adjustable or other voltage versions within the LM2575 family.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5V output at 1A is required from an input voltage between 4V and 40V. The TO-263-5 package offers a balance of thermal performance and board space efficiency for surface-mount designs. Consider the 52kHz switching frequency for applications where electromagnetic interference filtering is manageable without complex snubber networks.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 series of simple-to-use step-down switching regulators. The series includes standard voltage variants like the LM2575, military-grade LM1575, and high-voltage input LM2575HV models. All variants share similar control architectures but differ in input voltage ratings and operating temperature specifications.
