LM2852YMXAX-1.8

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXAX-1.8 is a synchronous step-down DC-DC converter manufactured by Texas Instruments, designed for high-efficiency power management in compact systems. It operates with an input voltage range of 2.85V to 5.5V and delivers a fixed output voltage of 1.8V at up to 2A load current. The device supports switching frequencies of 500kHz and 1500kHz, enabling the use of small external components. Packaged in a 14-pin HTSSOP with exposed pad, it integrates internal power switches and control circuitry to provide stable regulation under varying line and load conditions.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including suffixes such as NOPB or NO.A to ensure correct package type and temperature rating. Confirm that the EEPROM configuration matches the required output voltage specification before integration. Check manufacturer documentation for any obsolescence notices or recommended design updates associated with this specific revision code.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Choose this component when a fixed 1.8V output is required with minimal external passive components. The integrated EEPROM simplifies board layout compared to resistor-divider configurations. Consider the 1500kHz option if minimizing inductor size is critical, while the 500kHz setting may offer slightly better light-load efficiency. Ensure input voltage stays within the 2.85V to 5.5V operational window for proper regulation.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2852 family of Simple Switcher regulators, which are known for their ease of use and robust performance. The YMXAX suffix indicates a specific variant with factory-set output voltage via EEPROM, distinguishing it from adjustable versions. It serves as a drop-in replacement for older discrete solutions or other fixed-output buck converters in space-constrained designs.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2852YMXA-1.8/NOPB for standard adjustable variants requiring external feedback networks. For identical fixed-output functionality, verify availability of LM2852YMXAX-1.8/NOPB. Cross-reference pinouts and thermal characteristics when replacing with non-TI equivalents to ensure compatibility.
