LM2852XMXA-1.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852XMXA-1.0/NOPB is a synchronous buck regulator from Texas Instruments, part of the SIMPLE SWITCHER family. It integrates a 2A switch and operates at switching frequencies of 500kHz or 1500kHz. The device provides a fixed 1.0V output voltage with an initial accuracy of 1%. Key electrical parameters include a typical quiescent current of 0.85mA, a maximum output current of 2A, and a duty cycle up to 100%. It functions within an operating temperature range of -40°C to +125°C and utilizes a 14-pin PowerTSSOP package.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix '1.0' confirms the fixed 1.0V output variant. Ensure the 'NOPB' designation indicates lead-free and RoHS compliance. Confirm the HTSSOP/PowerTSSOP package type matches your PCB footprint requirements. Cross-reference the manufacturer's latest datasheet for any pinout revisions or updated thermal specifications before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.0V output is required without external feedback resistors. Choose the 500kHz frequency for smaller passive components or 1500kHz for faster transient response. Consider the 2A current limit for moderate load applications. Evaluate the 0.85mA quiescent current against system standby power budgets. Ensure the input voltage range supports the intended supply source.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2852 series of synchronous buck regulators. It shares architectural similarities with other SIMPLE SWITCHER products but is distinguished by its fixed output voltage options and integrated power stage. The series targets applications demanding high efficiency and compact solution sizes in surface-mount packages.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes may include other LM2852 variants with different fixed output voltages (e.g., LM2852XMXA-1.8/NOPB) if the voltage requirement changes. Verify compatibility with existing inductors and capacitors when substituting between different switching frequency options within the same family.
