LM2853MHX-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2853MHX-3.3/NOPB is a synchronous buck regulator from Texas Instruments, part of the SIMPLE SWITCHER family. It delivers a fixed 3.3 V output with a maximum load current of 3 A. The device operates at a switching frequency of 550 kHz and accepts an input voltage range of 3 V to 5.5 V. Packaged in a 14-pin PowerTSSOP (HTSSOP) with exposed pad for thermal management, it integrates internal power switches to minimize external component count.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete ordering code including suffixes such as NOPB and package variant MHX against the manufacturer's official datasheet. Confirm that the specific revision level matches your design requirements. Ensure compatibility with the intended PCB footprint and thermal dissipation strategy before finalizing procurement orders.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3 V rail is required with up to 3 A continuous current capability. It is suitable for designs prioritizing simplicity and reduced bill of materials over adjustable voltage flexibility. Consider the 550 kHz frequency trade-off between size and electromagnetic interference when choosing alternative regulators.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2853 series of synchronous buck converters. It shares architectural similarities with other SIMPLE SWITCHER regulators but is distinguished by its fixed 3.3 V output configuration. The series targets applications requiring robust performance in compact form factors without the need for complex feedback loop compensation.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2853MH-3.3/NOPB and LM2853MX-3.3/NOPB. Verify pinout compatibility and thermal characteristics when transitioning between tube and reel packaging variants or different package styles within the same functional family.
