LM2853MH-1.8

Voltage Regulators - DC DC Switching Regulators Overview

The LM2853MH-1.8 is a synchronous buck regulator manufactured by Texas Instruments, designed for high-efficiency power conversion in compact applications. It delivers a fixed 1.8 V output with a maximum load current of 3 A. The device operates from an input voltage range of 2.7 V to 5.5 V and integrates internal power switches to minimize external component count. It functions at a switching frequency of 550 kHz, enabling the use of small inductors and capacitors. The unit is housed in a 14-pin HTSSOP package, suitable for surface-mount assembly.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix (e.g., NOPB) against the datasheet to confirm lead-free compliance and exact pinout configuration. Ensure the ordering part number matches the required temperature grade and packaging format. Cross-reference the manufacturer's latest documentation to validate any revisions or obsolescence notices before finalizing procurement plans.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.8 V output is required with up to 3 A continuous current capability. It is appropriate for designs constrained by space due to its integrated switch topology and moderate switching frequency. Consider the input voltage range limits and thermal performance within the chosen HTSSOP package for the specific ambient operating environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2853 family of synchronous buck regulators from Texas Instruments. The family offers various fixed output voltages and current ratings tailored for different power density requirements. The MH variant specifically denotes the 14-pin HTSSOP package option, providing a balance between thermal dissipation and board space efficiency compared to smaller packages.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Check for LM2853MHX-1.8/NOPB as a potential equivalent depending on tape-and-reel versus tube packaging preferences. Verify that alternative devices support the same 3 A current rating and 550 kHz switching frequency to maintain existing passive component values.
