Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'HVMX' confirms the HTSSOP-14 surface-mount package variant distinct from TO-220 or TO-263 packages. Confirm 'NOPB' indicates lead-free and RoHS compliance status as per manufacturer specifications. Ensure the supplier documentation explicitly references the LM2575 family datasheet for accurate electrical parameter validation prior to integration.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a buck converter is required for inputs up to 60V with an adjustable output. The HTSSOP-14 package suits designs needing higher pin counts for additional control features compared to standard five-pin regulators. Consider the 52kHz switching frequency for balancing efficiency and passive component size in space-constrained applications.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2575 series of SIMPLE SWITCHER regulators, which are known for ease of use and robust performance in high-voltage environments. The 'HV' designation indicates high-voltage input capability, while 'ADJ' specifies the adjustable output configuration. The 'MX' suffix denotes the specific HTSSOP-14 packaging format used for surface-mount assembly.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2575HVMX-ADJ/NOPB is functionally equivalent to LM2575HVMX-ADJ. Cross-reference with LM2575HVS-ADJ/NOPB only if package compatibility (TO-263 vs HTSSOP) is addressed. Verify pinout alignment before substituting with non-TI equivalents.
