LM2575S-12-EV

Voltage Regulators - DC DC Switching Regulators Overview

The LM2575S-12-EV is a fixed-output buck switching regulator IC manufactured by EVVO. It provides a stable 12V output with a maximum current capacity of 2A. The device operates from an input voltage range up to 40V and utilizes a 150kHz switching frequency for efficient power conversion. Designed for surface-mount applications, it is housed in a TO-263-5L (D2PAK) package featuring five leads and a thermal pad. The component supports positive output configuration and functions as a non-synchronous step-down converter within an operating temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a fixed 12V output regulation suitable for standard logic and peripheral power supplies
• Utilizes a robust TO-263-5L package design to facilitate effective thermal dissipation during high-current operation
• Incorporates internal protection mechanisms typical of the LM2575 series architecture

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems requiring 12V rails
• Pre-regulation stages for downstream linear regulators
• General-purpose DC-DC conversion in industrial control equipment

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation on the component marking against EVVO specifications. Confirm the package type matches the required TO-263-5L footprint. Ensure the suffix indicates the correct fixed 12V output variant. Check RoHS compliance status if restricted substances are mandated for the assembly process.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required without external feedback resistor programming. Consider the 2A current limit and 40V maximum input voltage constraints. Evaluate the thermal requirements of the TO-263-5L package based on the expected load current and ambient temperature conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 family of simple switcher voltage regulators. The 'S' suffix typically denotes the surface-mount D2PAK package variant. The '12' identifier specifies the fixed 12V output voltage option. The 'EV' suffix appears to be a manufacturer-specific code or revision indicator associated with EVVO production.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Cross-reference with standard LM2575T-12 devices from other manufacturers for pin-compatible alternatives. Verify that substitute parts maintain the same 12V fixed output and 2A current rating.
