LM2576S-12-EV

Voltage Regulators - DC DC Switching Regulators Overview

The LM2576S-12-EV is a fixed-output step-down switching regulator IC manufactured by EVVO. It provides a stable 12V output with a maximum load current of 3A. The device operates from an input voltage up to 40V and utilizes a buck topology for efficient DC-DC conversion. Designed for surface-mount applications, it is housed in a TO-263-5L package (D2PAK variant). The internal oscillator sets the switching frequency at 52kHz. The component supports positive output configuration and functions within an ambient temperature range of -40°C to 125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a fixed 12V output regulation capability for consistent power delivery
• Supports high continuous load currents up to 3A for demanding subsystem requirements
• Features an integrated 52kHz oscillator to minimize external passive component count
• Includes thermal protection mechanisms inherent to the monolithic switching regulator design

Voltage Regulators - DC DC Switching Regulators Applications

• Industrial systems requiring secondary DC-DC conversion for subsystem supply voltages
• Embedded logic supply circuits on motherboards and control boards
• General-purpose power supplies utilizing standard input voltage rails
• Battery-powered equipment requiring regulated 12V distribution

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as EVVO when sourcing this specific part number. Confirm the suffix 'EV' aligns with the required packaging and environmental specifications. Ensure the TO-263-5L footprint matches the target PCB layout. Cross-reference the RoHS3 compliance status if restricted substance regulations apply to the final assembly. Validate the 40V maximum input rating against the system's worst-case input conditions.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required without external feedback network adjustments. The 3A current capacity suits moderate power applications where efficiency is prioritized over ultra-low quiescent current. The 40V input limit distinguishes it from higher-voltage variants like the LM2576HVS series. Consider the TO-263-5L package for adequate thermal dissipation in surface-mount designs. This regulator is suitable for non-synchronous applications where cost-effectiveness is a primary design constraint.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2576 series of switching regulators produced by EVVO. It represents the standard voltage rating variant, distinct from the HVS series which supports inputs up to 57V. The 'S' indicates the surface-mount package type. As a member of this family, it shares the fundamental buck converter architecture but is optimized for 40V input environments rather than high-voltage industrial buses.
