LM2853MHX-3.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2853MHX-3.0/NOPB is a synchronous step-down DC-to-DC converter from the SIMPLE SWITCHER series, manufactured by Texas Instruments (formerly National Semiconductor). It operates with an input voltage range of 3V to 5.5V and provides a fixed positive output of 3V at up to 3A. The device features a switching frequency of 550kHz and utilizes a 14-pin HTSSOP package with an exposed pad for thermal management.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Synchronous rectification design for improved efficiency
Fixed 3V output capability within specified input range
Integrated power switch and control circuitry

Voltage Regulators - DC DC Switching Regulators Applications

Automotive electronic systems
Industrial control equipment
Consumer electronic devices

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the manufacturer designation as Texas Instruments, as National Semiconductor was acquired. Confirm the suffix NOPB indicates RoHS compliance and lead-free construction. Ensure the HTSSOP-14 package type matches the target PCB footprint. Validate the fixed 3.0V output version against system requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact, high-efficiency buck regulator is needed for 3V to 5.5V input sources. The 3A output current rating suits moderate load applications. The 550kHz frequency allows for smaller external inductors compared to lower-frequency alternatives. Consider thermal performance due to the exposed pad requirement.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2853 family of SIMPLE SWITCHER regulators. It is functionally similar to variants like the LM2853MHX-3.3/NOPB but differs in the fixed output voltage setting. The MHX suffix denotes tape and reel packaging, while NOPB confirms environmental compliance.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include other LM2853 variants with different output voltages if the voltage level can be adjusted or if the specific 3V output is not critical. Verify pin compatibility and thermal characteristics before substitution.
