LM2575YWM

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575YWM is a monolithic integrated circuit providing step-down (buck) switching regulator functions. It operates with an input voltage range of 4V to 40V and delivers a fixed 12V output at up to 1A load current. The device features a 52kHz internal oscillator, eliminating the need for external frequency compensation components. It utilizes pulse-width modulation control mode and is housed in a 24-SOIC surface-mount package.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates all active functions for a simple buck converter design requiring minimal external components
• Includes internal frequency compensation and fixed 52kHz oscillation for simplified circuit layout
• Provides comprehensive protection mechanisms including thermal shutdown and current limiting

Voltage Regulators - DC DC Switching Regulators Applications

• Distributed power supply systems requiring efficient step-down conversion
• Pre-regulator circuits for linear post-regulators
• Efficient on-card regulation modules

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'YWM' corresponds to the Microchip Technology 24-SOIC package variant. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the fixed 12V output aligns with system voltage needs, as adjustable versions exist within the same series.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an input voltage between 4V and 40V. It is suitable for applications needing 1A continuous current with high efficiency. Consider the SOIC-24 package constraints for PCB space. Compare against adjustable variants if flexible output voltage is needed instead of the fixed configuration.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 series of Simple Switcher power regulators. The series is known for reducing design time and board space through integrated compensation and protection. The YWM suffix specifically denotes the surface-mount 24-pin SOIC package variant manufactured by Microchip Technology, distinct from through-hole or TO-263 packages.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2575BWM is a parameter-equivalent adjustable version in the same package. LM2592HVS-5.0/NOPB is listed as a similar alternative but differs in input voltage range and output configuration.
