Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix against official Texas Instruments documentation to confirm RoHS compliance and lead-free status. Ensure the ordering part number matches the required package variant and output configuration. Cross-reference datasheet revisions to validate pinout compatibility and electrical specifications before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when designing buck converters requiring high input voltages up to 60 V with moderate current demands. The fixed 150 kHz frequency allows for smaller passive components compared to lower-frequency alternatives. Consider the thermal performance of the TO-263 package for heat dissipation requirements in enclosed environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2593HV series of SIMPLE SWITCHER regulators. It shares architectural similarities with the LM2590HV and LM2592HV families but offers a higher 2 A output current capacity. The series is designed for efficient step-down conversion in industrial and communication applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2593HVS-5.0/NOPB provides a fixed 5 V output option within the same series. LM2592HVS-ADJ/NOPB offers similar functionality with a 2 A rating but may differ in specific thermal or packaging details.
