LM2575-12BWM

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575-12BWM-TR is a monolithic integrated circuit designed as a step-down (buck) switching regulator. It provides a fixed 12V output with a maximum load current of 1A. The device operates from an input voltage range of 4V to 40V and utilizes a 52kHz internal oscillator for efficient power conversion. It is housed in a 24-SOIC surface-mount package, suitable for compact designs requiring reliable DC-DC regulation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'BWM' against the manufacturer's official datasheet to confirm pinout and thermal pad configuration. Ensure the ordering code includes '-TR' if tape-and-reel packaging is required, as standard tubes may differ. Cross-reference the RoHS status and lead-free markings with the latest Microchip documentation prior to procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required at up to 1A with minimal external components. It is appropriate for applications where a 52kHz switching frequency allows for smaller passive components compared to lower-frequency alternatives. Consider thermal dissipation requirements based on the input-output voltage differential and load current.
