LM2852YMXAX-1.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXAX-1.0/NOPB is a synchronous step-down DC-DC converter from Texas Instruments' SIMPLE SWITCHER family. It operates with an input voltage range of 2.85V to 5.5V and provides a fixed positive output of 1.0V. The device supports a continuous output current of 2A and features adjustable switching frequencies of 500kHz or 1500kHz. Packaged in a 14-pin HTSSOP (PWP) with exposed pad, it functions as a single-output regulator suitable for space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'X-1.0' against official Texas Instruments documentation to confirm the fixed 1.0V output variant. Ensure the NOPB designation indicates lead-free compliance. Confirm package type matches HTSSOP PWP specifications. Cross-reference part numbers with TI's current product status to avoid obsolete components.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.0V rail is required within a 2.85V to 5.5V input window. The 2A current rating suits moderate load applications. Choose between 500kHz and 1500kHz frequencies based on passive component size constraints versus EMI requirements. Verify thermal performance in the HTSSOP package for the target ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 series of synchronous buck regulators. It shares architectural similarities with other SIMPLE SWITCHER devices but is distinguished by its fixed 1.0V output option. The series targets efficient power conversion in compact form factors, utilizing integrated MOSFETs to minimize external component count.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Official substitutes include LM2852YMXAX-1.3/NOPB for 1.3V output and LM2852YMXAX-3.3/NOPB for 3.3V output, maintaining identical pinouts and functionality. For legacy National Semiconductor parts, verify compatibility with the TI-rebranded equivalents.
