Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'NOPB' confirms lead-free and RoHS compliance as per Texas Instruments standards. Confirm the 'XMXA' designation matches the required HTSSOP-14 package variant with exposed pad. Ensure the '-1.8' indicates the fixed 1.8 V output version. Cross-reference the manufacturer part number against official TI documentation to avoid counterfeit components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required within a 2.85 V to 5.5 V input range. Consider the 2 A current capability and available switching frequencies for filter component sizing. Evaluate the HTSSOP-14 package constraints for PCB layout and thermal management requirements compared to other LM2852 variants.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 family of synchronous buck regulators from Texas Instruments. It shares core topology with variants like LM2852XMXA-25-NOPB and LM2852YMXA-1.5/NOPB but differs in output voltage configuration. The family is characterized by high efficiency and compact footprint, suitable for various portable and industrial applications requiring reliable step-down conversion.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2852XMXA-1.8 (without NOPB suffix) if lead-free compliance is not critical. Other LM2852 variants with different output voltages may serve as functional replacements if voltage adjustment is feasible via external resistors, though fixed-output versions offer simpler design.
