LM2853MHX-2.5/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2853MHX-2.5/NOPB is a fixed-output synchronous buck regulator manufactured by Texas Instruments, formerly National Semiconductor. It provides a fixed 2.5 V output with a maximum load current of 3 A. The device operates from an input voltage range of 3 V to 5.5 V and utilizes a TSSOP-14 package for surface-mount installation. It features a switching frequency of 0.55 MHz and supports an operating temperature range from -40 °C to +125 °C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous rectification architecture for improved efficiency
Fixed 2.5 V output configuration
Integrated power switches for compact design

Voltage Regulators - DC DC Switching Regulators Applications

Portable electronics requiring efficient step-down conversion
Battery-powered systems with single-cell lithium inputs
Embedded logic supply regulation

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix 'NOPB' indicates lead-free and RoHS compliance. Ensure the package type matches the required TSSOP-14 footprint and that the thermal rating aligns with the intended application environment.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 2.5 V rail is required at up to 3 A from a 3 V to 5.5 V source. The synchronous topology offers higher efficiency compared to non-synchronous alternatives. Verify that the TSSOP-14 package size fits the PCB layout constraints and that the thermal dissipation capabilities are sufficient for the expected load conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM285x family of synchronous buck regulators. It shares architectural similarities with other members like the LM2854 but differs in output current capability and specific pin configurations. The family targets low-voltage, high-current applications in portable devices.
