Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'HVM' indicates the high-voltage variant in the 14-pin SOIC package. Confirm RoHS compliance via the NOPB designation. Ensure the supplier source matches Texas Instruments documentation to avoid counterfeit components. Check datasheet revisions for any pinout or electrical parameter updates before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when input voltages exceed 40 V, as standard LM2574 variants are limited to 40 V. The fixed 5.0 V output removes the need for external feedback resistors. Consider the 14-pin SOIC package for surface-mount assembly requirements. Evaluate thermal performance at higher ambient temperatures due to the extended operating range.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2574HV family, which extends the input voltage capability beyond the standard LM2574 series. It shares the same internal architecture and control logic but is rated for higher input potentials. The HVM suffix denotes the specific package and temperature grade combination offered by Texas Instruments.
