Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer origin carefully, as the LM2576 family is widely produced by multiple vendors including Texas Instruments and onsemi. Confirm that the specific part number corresponds to the TAEJIN Technology variant rather than other manufacturers' equivalents. Ensure the package type matches the required TO-220-5 through-hole configuration for your design. Check datasheet revisions to confirm pinout compatibility if substituting existing designs.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters requiring high input voltage tolerance up to 60 V and continuous 3.0 A load capacity. The adjustable output version allows flexibility in setting precise voltage levels between 1.23 V and 37 V. Consider the TO-220-5 package for through-hole assembly needs and adequate thermal dissipation. The 52 kHz switching frequency balances efficiency and component size requirements for standard inductor selections.
