LM2852XMXAX-1.5

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852XMXAX-1.5 is a synchronous step-down DC-to-DC converter manufactured by Texas Instruments. It operates with an input voltage range of 2.85 V to 5.5 V and provides a fixed output voltage of 1.5 V. The device supports a maximum output current of 2 A and features a switching frequency of 1.5 MHz. It is housed in a 14-pin HTSSOP package with an exposed pad (PWP) for thermal management.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the suffix, such as /NOPB, which indicates lead-free status. Confirm the specific output voltage variant matches the design requirement, as the LM2852 family offers multiple factory-set options. Ensure the HTSSOP package type aligns with the PCB footprint specifications before ordering.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.5 V output is required from a 2.85 V to 5.5 V input source. The 2 A current capability suits moderate load applications. Consider the 1.5 MHz switching frequency for smaller passive component sizes compared to lower-frequency alternatives. Verify thermal performance requirements given the 14-pin HTSSOP package constraints.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 series of SIMPLE SWITCHER buck regulators. The series is characterized by high integration and factory-set output voltages, reducing external component count. The XMXA suffix denotes the specific package and temperature grade configuration within the broader product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2852 variants with different fixed output voltages, such as LM2852XMXAX-3.3/NOPB, if the voltage requirement changes. Cross-referencing with similar 2 A synchronous buck regulators from other manufacturers requires verifying pin compatibility and electrical parameters.
