LM2675LD-3.3/NOPB

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675LD-3.3/NOPB is a SIMPLE SWITCHER® step-down voltage regulator manufactured by Texas Instruments, designed for high-efficiency power conversion within a compact footprint. It operates with an input voltage range of 6.5V to 40V and provides a fixed 3.3V output at up to 1A load current. The device integrates a 1.1A switch and utilizes a 260kHz switching frequency to minimize external component size. Housed in a 16-pin WSON package, it supports operation from -40°C to +125°C, offering robust performance for space-constrained applications requiring reliable DC-DC regulation.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'LD' indicates the WSON-16 package variant distinct from other pinouts. Confirm the '-3.3' designation ensures the fixed 3.3V output version rather than adjustable or other voltage options. Ensure NOPB compliance matches project RoHS requirements. Cross-reference the manufacturer's latest datasheet to confirm active status and any recent packaging updates before finalizing procurement specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a fixed 3.3V output is required from an input range up to 40V with moderate current demands. The WSON-16 package suits designs prioritizing minimal PCB area over through-hole mounting. Consider the 260kHz switching frequency for balancing efficiency and passive component size. Ensure thermal management strategies align with the 1A continuous current capability and ambient operating conditions specified in the datasheet.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 series of SIMPLE SWITCHER regulators, which are known for integrating power switches to simplify buck converter designs. The LD suffix specifically denotes the small-outline WSON package, differentiating it from SOIC or DIP variants like the LM2675M or LM2675N. This series targets applications needing high efficiency and low external component counts compared to traditional linear regulators or discrete switching solutions.
