LM2675LD-5.0

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675LD-5.0/NOPB is a SIMPLE SWITCHER® step-down voltage regulator from Texas Instruments, designed for high-efficiency power conversion with a minimal component count. It operates within an input voltage range of 6.5V to 40V and provides a fixed 5.0V output at up to 1A load current. The device integrates a 0.5A internal switch and utilizes a 260kHz switching frequency to allow for smaller external inductors and capacitors. It features thermal shutdown and current limit protection, housed in a compact 16-pin WSON package suitable for space-constrained applications.

• High efficiency operation across wide input ranges
• Built-in thermal shutdown and current limiting

Voltage Regulators - DC DC Switching Regulators Applications

• Point-of-load regulation for embedded systems
• Battery-powered equipment requiring efficient step-down
• Industrial control modules with 24V or 48V buses
• Telecommunications infrastructure power distribution

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix NOPB indicates lead-free/RoHS compliance when ordering. Confirm the LD package variant matches your PCB footprint requirements. Ensure the -5.0 designation aligns with your specific voltage needs, as other fixed voltages are available in the same series. Cross-reference datasheet revision dates for any pinout or electrical characteristic updates before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this part when a fixed 5V output is required from a 6.5V to 40V source. The 16-pin WSON package offers a small footprint compared to traditional SOIC or DIP options. Consider the 260kHz frequency trade-off between component size and EMI. Verify that the 1A output current meets your system's peak load demands without exceeding thermal limits under worst-case ambient conditions.

Voltage Regulators - DC DC Switching Regulators Part Context

This component belongs to the LM2675 family of SIMPLE SWITCHER regulators, which includes adjustable and various fixed voltage variants. It shares core architecture with the LM2676 (3A) and LM2674 (0.5A) but is optimized for 1A applications. The LD suffix specifically denotes the 16-pin WSON package, distinguishing it from the M (SOIC) or N (DIP) package options available in the broader product line.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

LM2675LD-5.0/NOPB is the direct equivalent with environmental compliance. LM2675M-5.0/NOPB offers the same electrical performance in an SOIC-8 package. LM2675N-5.0/NOPB provides through-hole mounting capability. For higher current needs, consider the LM2676 series; for lower current, the LM2674 series.
