Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575-12YWM-TR

LM2575-12YWM-TR

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575-12YWM-TR is a monolithic integrated circuit step-down (buck) switching voltage regulator manufactured by Microchip Technology. 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 fixed 52kHz internal oscillator. It is housed in a 24-SOIC surface-mount package and supports an operating junction temperature range of -40°C to +85°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrated buck topology with fixed frequency oscillation for simplified design
Internal frequency compensation reduces external component count
Built-in thermal shutdown and current limiting for system protection

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in distributed power systems
Pre-regulator stages for linear post-regulators
Efficient step-down conversion from higher bus voltages

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'TR' indicates tape-and-reel packaging, distinct from tube-packaged variants like the standard YWM. Confirm RoHS compliance status as specifications may vary by production lot or revision. Ensure the specific Microchip datasheet version matches the required electrical tolerances and thermal characteristics for the target application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 12V output is required at up to 1A with minimal external components. The SOIC-24 package suits applications needing higher pin counts for control features compared to TO-220/TO-263 versions. Verify that the 52kHz switching frequency aligns with EMI constraints and inductor size requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2575 series of simple, high-efficiency step-down regulators. Unlike adjustable versions, the '-12' designation fixes the output voltage at 12V. The 'YWM' indicates the 24-pin SOIC package, while '-TR' specifies the reel packaging format for automated assembly processes.
