LM2675LDX-ADJ

Voltage Regulators - DC DC Switching Regulators Overview

The LM2675LDX-ADJ is a SIMPLE SWITCHER power converter from Texas Instruments, functioning as a high-efficiency 1A step-down voltage regulator. It utilizes a buck topology with a fixed switching frequency of 260 kHz. The device accepts an input voltage range of 6.5 V to 40 V and provides an adjustable output voltage ranging from 1.21 V to 37 V. It supports a maximum continuous output current of 1 A. The component is housed in a WSON-16 package and is rated for operation within a junction temperature range of -40°C to +125°C.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the suffix 'LDX' corresponds to the specific tape-and-reel packaging variant of the LM2675LD-ADJ. Confirm that the WSON-16 package dimensions match your PCB footprint requirements. Ensure the supplier provides original manufacturer documentation to validate the NOPB lead-free status and RoHS compliance before finalizing procurement.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for high-efficiency step-down conversion up to 1 A. The adjustable output allows flexibility for various load voltages between 1.21 V and 37 V. Consider the WSON-16 package size constraints and thermal dissipation capabilities relative to your ambient operating conditions and expected load currents.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the LM2675 family of SIMPLE SWITCHER regulators, which are designed for high-efficiency DC-DC conversion. The family includes fixed-output variants (e.g., 3.3V, 5V) and adjustable versions. The LD suffix indicates the WSON-16 surface-mount package, distinguishing it from SOIC or DIP alternatives like the LM2675M or LM2675N series.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Direct substitutes include LM2675LD-ADJ/NOPB for identical electrical specifications and package. For pin-compatible alternatives with different packages, consider LM2675MX-ADJ (SOIC-8) or LM2675N-ADJ (DIP-8), noting that thermal performance and board space requirements will differ significantly.
