Voltage Regulators - DC DC Switching Regulators datasheet and documents for LM2575D2T-15R4G

LM2575D2T-15R4G

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575D2T-15R4G is a monolithic integrated circuit from onsemi, belonging to the LM2575 series of switching regulators. It functions as a step-down (buck) DC-to-DC converter with a fixed 15V output voltage and a maximum output current capability of 1A. The device operates at a standard switching frequency of 52kHz and supports an input voltage range from 4V to 40V. Packaged in a surface-mount TO-263-6 (D2PAK) format, it is designed for efficient power management within an operating temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Integrates a fixed-frequency 52kHz oscillator for simplified external component selection
Includes internal thermal shutdown and current limiting protection mechanisms
Features a high-efficiency monolithic buck topology for direct voltage reduction

Voltage Regulators - DC DC Switching Regulators Applications

Point-of-load regulation in distributed power supply architectures
Pre-regulation stages for downstream linear regulators
General-purpose step-down conversion for industrial control systems

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix R4G against the manufacturer's official datasheet to confirm tape-and-reel packaging specifications and marking codes. Ensure the procurement source provides valid RoHS compliance documentation consistent with the component's environmental standards. Cross-reference the part number with the latest onsemi product change notices to confirm manufacturing status and availability constraints.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 15V output is required from an input rail between 4V and 40V. The TO-263 package offers suitable thermal dissipation for 1A continuous loads without excessive heatsinking. Consider the 52kHz switching frequency for balancing filter size and efficiency. Verify that the application environment remains within the specified -40°C to +125°C junction temperature range for reliable operation.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the widely adopted LM2575 family of simple switchers, known for reducing design complexity in buck converter applications. The D2T variant specifically denotes the surface-mount D2PAK/TO-263 package style, differing from through-hole alternatives like the LM2575T or LM2575S. The '15' indicates the fixed 15V output version, while 'R4G' typically signifies reel packaging and lead-free composition.
