LM2575BWM-TR

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575BWM-TR is a monolithic integrated circuit step-down switching regulator manufactured by Microchip Technology. It operates as a buck converter with an input voltage range of 4V to 40V and delivers a maximum output current of 1A. The device utilizes a fixed frequency internal oscillator operating at 52kHz, eliminating the need for external frequency compensation components. It features an adjustable output voltage configuration ranging from 1.23V to 37V. The component is housed in a 24-SOIC surface-mount package and supports a junction temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix and manufacturer documentation carefully, as availability status may vary across distributors. Confirm that the received component matches the exact part number and package type specified in the official datasheet. Check for any obsolescence notices or lifecycle changes issued by Microchip Technology prior to finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a non-synchronous buck regulator with adjustable output voltage is required. Ensure the application input voltage stays within the 4V to 40V range and the load current does not exceed 1A. Consider the 24-SOIC package size for PCB layout constraints and verify thermal management requirements for the intended operating environment.
