LM2672LD-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2672LD-ADJ is a monolithic DC-DC step-down switching regulator from the SIMPLE SWITCHER family, manufactured by Texas Instruments. It utilizes LMDMOS technology to deliver a continuous output current of 1 A with high efficiency exceeding 90%. The device operates within an input voltage range of 6.5 V to 40 V and provides an adjustable output voltage spanning 1.21 V to 37 V. It functions at a fixed internal switching frequency of 260 kHz, enabling the use of compact external components. The unit is housed in a 16-pin HVSON or LLP package and supports operation across a temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Feature Summary

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify component authenticity through authorized distributors as counterfeits exist. Confirm RoHS compliance status and lead times due to potential lifecycle changes. Ensure proper ESD handling during storage and assembly. Validate package marking against official datasheet specifications to avoid substitution errors.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a 1 A buck converter is required with an input voltage up to 40 V. The 260 kHz frequency allows smaller inductors compared to lower-frequency alternatives. Consider the 16-pin LLP/HVSON package for space-constrained designs requiring robust thermal performance.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2672 series of SIMPLE SWITCHER regulators. It shares functional similarities with other members like the LM2672M and LM2672MX but differs in packaging. The LD suffix typically denotes a specific leadless or small-outline package variant designed for surface-mount applications.
