LM2852YMXAX-3.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852YMXAX-3.0/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 3.0V output at up to 2A load current. The device supports adjustable switching frequencies of 500kHz or 1500kHz, selectable via the EN pin. Packaged in a 14-pin HTSSOP with exposed pad for thermal dissipation, it functions within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the exact suffix 'YMXAX-3.0/NOPB' against official Texas Instruments documentation to confirm the specific 3.0V fixed output variant. Ensure compatibility with the required switching frequency setting via the enable pin configuration. Cross-reference the datasheet revision history for any updates regarding thermal performance or electrical characteristics before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.0V output is required from a 2.85V to 5.5V input source. Consider the 14-pin HTSSOP package constraints for PCB layout and thermal management. Evaluate the need for 500kHz versus 1500kHz operation based on external inductor size and transient response requirements. Confirm that the 2A continuous current rating meets the maximum load demand of the target application circuit.
