LM2672LD-5.0/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2672LD-5.0/NOPB is a high-efficiency 1A step-down voltage regulator from the SIMPLE SWITCHER family by Texas Instruments. It operates with an input voltage range of 6.5V to 40V, providing a fixed 5.0V output. The device integrates a 0.5A internal switch and supports switching frequencies up to 275kHz. It features adjustable current limit protection and thermal shutdown. The component is housed in a 16-pin HVSON package (SOLCC16) and is rated for operation between -40°C and 125°C junction temperature.

Voltage Regulators - DC DC Switching Regulators Feature Summary

• Integrates a 0.5A power switch for efficient step-down conversion
• Includes adjustable current limit and thermal shutdown protection
• Supports switching frequencies up to 275kHz for compact passive design

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring high efficiency
• Industrial control system power supplies

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LD' indicates the 16-pin HVSON package variant rather than standard SOIC versions. Confirm the 'NOPB' designation ensures lead-free compliance and RoHS adherence as per manufacturer specifications. Cross-reference the fixed 5.0V output requirement against available adjustable or other fixed voltage variants within the same series to ensure correct functional selection.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V output is required from inputs up to 40V with moderate load currents. The 16-pin HVSON package offers a smaller footprint compared to traditional SOIC packages but requires appropriate PCB thermal management. Ensure the application can accommodate the 275kHz switching frequency noise profile and that the external inductor and capacitor values match the datasheet recommendations for stability.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2672 series of SIMPLE SWITCHER power converters, designed for high-efficiency DC-DC step-down applications. It shares architectural similarities with the LM2671 and LM2675 but is distinguished by its 1A output capability and specific packaging options like the LD suffix for the 16-pin HVSON form factor.
