Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2574M-15/NOPB

LM2574M-15/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2574M-15/NOPB is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments, designed for high-efficiency DC/DC conversion. It operates with an input voltage range of 4 V to 40 V and provides a fixed 15 V output at up to 500 mA. The device integrates a 150 kHz oscillator for compact external component sizing and includes thermal shutdown and current limit protection. Packaged in a 14-pin SOIC-Wide (MSOP) surface-mount format, it supports operation from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a fixed-frequency internal oscillator for simplified design
Includes built-in thermal shutdown and current limiting protection
Requires minimal external components for standard buck topology

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation for embedded systems
Battery-powered equipment requiring efficient step-down conversion
General-purpose DC/DC power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against the manufacturer datasheet to confirm package type and temperature rating. Ensure the ordering part number matches the required output voltage variant within the LM2574 family. Cross-reference the RoHS compliance status with the latest official documentation before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15 V output is required from a 4 V to 40 V input source. It is suitable for applications needing moderate current capacity with minimal external circuitry. Consider the SOIC-Wide package constraints for PCB layout and thermal management requirements.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574 series of adjustable and fixed-output step-down regulators. It shares core architecture with other variants like the LM2574M-12/NOPB but differs in fixed output voltage. The 'M' suffix indicates the SOIC-Wide package, distinguishing it from through-hole or HV versions.
