LM2852XMXA-3.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2852XMXA-3.0/NOPB is a synchronous step-down DC/DC converter from Texas Instruments, operating within an input voltage range of 2.85 V to 5.5 V. It provides a fixed 3.0 V output with a maximum load current of 2 A. The device supports adjustable switching frequencies of 500 kHz and 1.5 MHz, enabling optimization for efficiency or component size. Packaged in a 14-pin HTSSOP with an exposed pad, it operates reliably across a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'NOPB' confirms lead-free and RoHS compliance status as per manufacturer documentation. Confirm the 'XMXA' package designation matches the required 14-HTSSOP footprint and thermal pad specifications for your PCB layout. Ensure the fixed 3.0 V output variant aligns with system voltage requirements before procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.0 V rail is required from a single-cell lithium-ion or similar 2.85 V–5.5 V source. The choice between 500 kHz and 1.5 MHz frequencies should be driven by inductor size constraints versus EMI sensitivity. Verify that the 2 A continuous current capability meets the peak load demands of the downstream circuitry without exceeding thermal limits.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2852 family of SIMPLE SWITCHER regulators. It shares architectural similarities with variants offering different fixed output voltages, such as the LM2852XMXA-3.3/NOPB. The family is characterized by integrated power switches and support for external frequency adjustment, targeting compact power solutions in portable and industrial applications.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2852XMXA-3.3/NOPB offers identical electrical characteristics except for a fixed 3.3 V output. LM2852YMXA-3.0/NOPB provides the same 3.0 V output but may differ in package marking or minor manufacturing revisions. Verify pinout compatibility and thermal performance when substituting.
