Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., MTCX vs SD) to confirm the correct package type, as TSSOP and WSON variants exist within the LM5000 family. Ensure the NOPB designation confirms lead-free compliance if required by your assembly process. Cross-reference the exact part number against the manufacturer's latest datasheet to confirm pinout compatibility and thermal characteristics before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a wide input voltage range up to 40V is required for non-isolated boost or flyback applications. The fixed 300kHz to 700kHz frequency offers a balance between efficiency and external component size. Consider the 16-TSSOP package for surface-mount assembly needs where moderate thermal dissipation is sufficient for the intended load current.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM5000 series of high-voltage switch-mode regulators. It is distinct from other TI regulators by its specific support for both boost and flyback configurations within a single IC. The series is engineered for robust performance in industrial and automotive environments requiring reliable power conversion from variable input sources.
