LM2853MH-1.5/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2853MH-1.5/NOPB is a high-efficiency, low-voltage 3A synchronous step-down DC-DC converter from the SIMPLE SWITCHER series, originally developed by National Semiconductor and now managed by Texas Instruments. Designed for compact power solutions, it operates from 3.3V or 5V input sources to provide regulated output voltages, such as the fixed 1.5V variant indicated in the part number. The device integrates internal power switches to minimize external component count, supporting high current loads while maintaining small form factors suitable for space-constrained digital integrated circuits.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify that the manufacturer designation aligns with current Texas Instruments production standards, as National Semiconductor assets were acquired. Confirm the suffix /NOPB indicates lead-free compliance and RoHS adherence. Ensure the MH package code matches the required HTSSOP footprint for your PCB layout. Cross-reference the specific -1.5 output voltage setting against your design requirements.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 1.5V output at up to 3A is required from a 3.3V or 5V rail. It is appropriate for designs prioritizing board space reduction due to its high integration level. Consider thermal management capabilities inherent to the HTSSOP package if operating near maximum load currents in enclosed environments.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the SIMPLE SWITCHER family of switching regulators, which emphasizes ease of design implementation through reduced external component counts. The LM2853 specifically targets low-voltage, high-current applications where efficiency and size are critical constraints compared to traditional linear regulators or asynchronous buck converters.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official cross-reference lists for direct equivalents. Verify pin compatibility and electrical specifications before substituting with other synchronous buck regulators from Texas Instruments or third-party manufacturers.
