LM2575S-ADJ-EV

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575S-ADJ-EV is an adjustable step-down DC-DC switching regulator manufactured by EVVO. It operates with a maximum output voltage of 37V and supports up to 2A of output current. The device utilizes a buck topology with asynchronous rectification and switches at a frequency of 150kHz. It is housed in a TO-263-6 (D2PAK) package featuring five leads plus a tab. The component is rated for an operating junction temperature range of -40°C to 125°C.

• Motherboard logic supply voltage generation
• General-purpose DC-DC step-down regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation matches EVVO specifications rather than legacy National Semiconductor or TI datasheets, as pinouts and electrical characteristics may differ between original and alternative source components. Confirm the specific suffix 'EVVO' aligns with the required quality grade and packaging format for your production line. Ensure the asynchronous rectifier design meets your efficiency requirements compared to modern synchronous alternatives.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when an adjustable buck converter is required with a 2A current capacity and standard 150kHz switching frequency. The TO-263-6 package provides adequate thermal dissipation for moderate power applications without requiring extensive external heatsinking. Consider the asynchronous nature of the regulator for cost-sensitive designs where peak efficiency at light loads is not the primary constraint.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 series family, which offers high-efficiency replacements for traditional three-terminal linear regulators. The series includes fixed output variants such as 3.3V, 5V, and 12V, alongside the adjustable version presented here. The design aims to reduce heat sink size and overall system volume while maintaining reliable voltage regulation under varying load conditions.
