Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'MX' corresponds to the SOIC-8 tape-and-reel packaging configuration as defined by Texas Instruments documentation. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance status according to the latest manufacturer specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 5.0 V output is required from inputs up to 60 V with moderate current demands around 1 A. The SOIC-8 package suits applications requiring surface-mount assembly. Ensure the 52 kHz switching frequency aligns with the electromagnetic interference constraints and passive component selection requirements of the target circuit design.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575HV family of SIMPLE SWITCHER converters, designed for high-voltage step-down applications. It serves as a robust alternative to linear regulators in scenarios where significant voltage drops occur between the source and load, offering improved efficiency through switched-mode operation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct pin-compatible substitutes within the same family include the LM2575HVM-ADJ/NOPB for adjustable output or other fixed voltage variants such as the LM2575HVM-3.3/NOPB. Verify package compatibility and thermal characteristics when cross-referencing with older legacy versions lacking the HV designation.
