LM2832XSD/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2832XSD/NOPB is a high-frequency synchronous buck DC-DC converter manufactured by Texas Instruments. It integrates a 2.0 A power switch and operates with a fixed switching frequency of 1.6 MHz. The device provides an adjustable output voltage ranging from 600 mV to 4.5 V, supporting single-output configurations. Designed for surface-mount installation in a WSON-6 package, it ensures reliable performance across an extended temperature range from -40°C to +125°C. This regulator is optimized for space-constrained applications requiring efficient step-down conversion.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the complete part number including the NOPB suffix to confirm lead-free compliance and specific tape-and-reel packaging options such as Cut Tape or MouseReel. Ensure the WSON-6 footprint matches the design layout. Confirm that the input voltage source remains within the operational limits defined in the official datasheet to prevent device damage during procurement validation.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution with 2.0 A continuous current capability is required. The fixed 1.6 MHz frequency allows for smaller inductors compared to lower-frequency alternatives. Consider the WSON-6 package constraints for thermal dissipation. Verify that the load requirements do not exceed the integrated switch rating and that the desired output voltage falls within the 600 mV to 4.5 V adjustment window.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the LM2832 series of synchronous step-down regulators. It shares functional similarities with other members like the LM2831 and LM2833 but differs in output current capacity and package type. The LM2832 specifically targets applications needing higher current density than the LM2831 while utilizing a smaller footprint than the LM2833.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

For obsolete variants, the LM2831ZSD/NOPB is listed as a parameter-equivalent alternative, though it offers reduced current capacity. Designers should verify pin compatibility and thermal characteristics when substituting with other family members or cross-brand solutions.
