Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as EVVO on official datasheets, as this part belongs to the LM2576 family originally developed by National Semiconductor. Confirm the specific suffix 'EV' corresponds to the intended packaging and compliance specifications. Ensure the TO-263-5L package matches your PCB footprint requirements before finalizing orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 12V output is required from an input voltage up to 57V. The 3A current rating suits moderate power loads. Consider the TO-263-5L package for surface mount assembly. Verify that the 52kHz switching frequency aligns with your electromagnetic interference constraints and inductor selection guidelines.

Voltage Regulators - DC DC Switching Regulators Part Context

This component is part of the LM2576 series, which serves as a replacement for three-terminal linear regulators. The 'HV' variant specifically denotes high-voltage input capability, extending the operational range beyond standard versions. The EVVO branding indicates the current manufacturer producing this equivalent part number.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Compatible substitutes include the LM2576HV-12 from other manufacturers offering identical pinouts and electrical characteristics. Verify that any replacement maintains the 57V input limit and 3A output current specification.
